The LT
®
6015/LT6016/LT6017 are single/dual/quad rail-to-
rail input operational amplifiers with input offset voltage
trimmed to less than 50µV. These amplifiers operate on
single and split supplies with a total voltage of 3V to 50V
and draw only 315µA per amplifier. They are reverse
battery protected, drawing very little current for reverse
supplies up to 50V.
The Over-The-Top
®
input stage of the LT6015/LT6016/
LT6017 is designed to provide added protection in tough
environments. The input common mode range extends
from V to V+ and beyond: these amplifiers operate with
inputs up to 76V above V independent of V+. Internal
resistors protect the inputs against transient faults up
to 25V below the negative supply. The LT6015/LT6016/
LT6017 can drive loads up to 25mA and are unity-gain
stable with capacitive loads as large as 200pF. Optional
external compensation can be added to extend the capaci-
tive drive capability beyond 200pF.
The LT6015 is offered in a 5-lead SOT package. The LT6016
dual op amp is available in an 8-lead MSOP package. The
LT6017 is offered in a 22-pin leadless DFN package.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Voltages applied are with respect to V. The inputs are tested to
the Absolute Maximum Rating by applying –25V (relative to V) to each
input for 10ms. In general, faults capable of sinking current from either
input should be current limited to under 10mA. See the Applications
Information section for more details.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage and
how many amplifiers are shorted.
Note 4: The LT6015I/LT6016I/LT6017I are guaranteed functional over the oper-
ating temperature range of –40°C to 85°C. The LT6015H/LT6016H/LT6017H are
guaranteed functional over the operating temperature range of –40°C to 125°C.
The LT6015MP/LT6016MP/LT6017MP are guaranteed functional over the
junction temperature range of –55°C to 150°C. Junction temperatures greater
than 125°C will promote accelerated aging. The LT6015/LT6016/LT6017 has a
demonstrated typical performance beyond 1000 hours at TJ = 150°C.
Note 5: The LT6015I/LT6016I/LT6017I are guaranteed to meet specified
performance from –40°C to 85°C. The LT6015H/LT6016H/LT6017H are
guaranteed to meet specified performance from –40°C to 125°C. The
LT6015MP/LT6016MP/LT6017MP are guaranteed to meet specified
performance with junction temperature ranging from –55°C to 150°C.
Note 6: Test accuracy is limited by high speed test equipment repeatability. Bench
measurements indicate the input offset current in the Over-The-Top configuration
is typically controlled to under ±50nA at 25°C and ±150nA over temperature.
Note 7: The Reverse Supply voltage is tested by pulling 25μA/Amplifier out
of the V+ pin while measuring the V+ pin’s voltage with both inputs and V
grounded, verifying V+ < –50V.

Supply Voltage
The positive supply pin of the LT6015/LT6016/LT6017
should be bypassed with a small capacitor (typically 0.1μF)
as close to the supply pins as possible. When driving
heavy loads an additional 4.7μF electrolytic capacitor
should be added. When using split supplies, the same is
true for the V supply pin.
The LT6017 consists of two dual amplifier dice assembled
in a single DFN package which share a common substrate
(V). While the V pins of the quad (pins 16 and 18) must
always be tied together and to the exposed pad underneath,
the V+ power supply pins (pins 5 and 7) may be supplied
independently. The B and C channel amplifiers are supplied
through V+ by pin 7, and the A and D channel amplifiers are
supplied by pin 5. If pin 5 and pin 7 are not tied together
and are biased independently, each V+ pin should have
their own dedicated supply bypass to ground.
Shutdown
While there are no dedicated shutdown pins for the LT6015/
LT6016/LT6017, the amplifiers can effectively be shut down
into a low power state by removing V+. In this condition
the input bias current is typically less than 1nA with the
inputs biased between V and 76V above V, and if the
inputs are taken below V, they appear as a diode in series
with 1k of resistance. The output may be pulled up to 50V
above the V+ power supply in this condition (See Figure 1).
Pulling the output pin below V will produce unlimited
current and can damage the part.
Reverse Battery
The LT6015/LT6016/LT6017 are protected against reverse
battery voltages up to 50V. In the event a reverse battery
condition occurs, the supply current is typically less
than 5µA (assuming the inputs are biased within a diode
drop from V). For typical single supply applications with
ground referred loads and feedback networks, no other
precautions are required. If the reverse battery condition
results in a negative voltage at the input pins, the current
into the pin should be limited by an external resistor to
less than 10mA.
Inputs
Referring to the Simplified Schematic, the LT6015/LT6016/
LT6017 has two input stages: a common emitter differential
input stage consisting of PNP transistors Q1 and Q2 which
operate when the inputs are biased between V and 1.5V
below V+, and a common base input stage consisting of
PNP transistors Q3 to Q6 which operate when the common
mode input is biased greater than V+ –1.5V. This results
in two distinct operating regions as shown in Figure 2.
For common mode input voltages approximately 1.5V or
more below the V+ supply (Q1 and Q2 active), the com-
mon emitter PNP input stage is active and the input bias
current is typically under ±2nA. When the common mode
input is within approximately 1V of the V+ supply or higher

(Over-The-Top operation), Q9 begins to turn on diverting
bias current away from the common emitter differential
input pair to the current mirror consisting of Q11 and Q12.
The current from Q12 will bias the common base differential
input pair consisting of Q3 to Q6. Because the Over-The-Top
input pair is operating in a common base configuration,
the input bias current will increase to about 14μA. Both
input stages have their voltage offsets trimmed tightly and
are specified in the Electrical Characteristics table.
The inputs are protected against temporary excursions to
as much as 25V below V by internal 1k resistor in series
with each input and a diode from the input to the negative
supply. Adding additional external series resistance will
extend the protection beyond 25V below V. The input
stage of the LT6015/LT6016/LT6017 incorporates phase
reversal protection to prevent the output from phase
reversing for inputs below V.
There are no clamping diodes between the inputs. The
inputs may be over-driven differentially to 80V without
damage, or without drawing appreciable input current.
Figure 1 summarizes the kind of faults that may be applied
to the LT6015/LT6016/LT6017 without damage.
Over-The-Top Operation Considerations
When the input common mode of the LT6015/LT6016/
LT6017 is biased near or above the V+ supply, the amplifier
is said to be operating in the Over-The-Top configuration.
The differential input pair which control amplifier operation
is common base pair Q3 to Q6 (refer to the Simplified
Schematic). If the input common mode is biased between
V and approximately 1.5V below V+, the amplifier is said
to be operating in the normal configuration. The differential
input pair which control amplifier operation is common
emitter pair Q1 and Q2.
A plot of the Over-The-Top Transition region vs Temperature
(the region between normal operation and Over-The-Top
operation) on a 5V single supply is shown in Figure 2.
Some implications should be understood about Over-
The-Top operation. The first, and most obvious is the
input bias currents change from under ±2nA in normal
operation to 14µA in Over-The-Top operation as the input
stage transitions from common emitter to common base.
Even though the Over-The-Top input bias currents run
around 14 µA, they are very well matched and their offset
is typically under ±100nA.
The second and more subtle change to amplifier operation
is the differential input impedance which decreases from
1MΩ in normal operation, to approximately 3.7kΩ in
Over-The-Top operation (specified as RIN in the Electrical
Characteristics table). This resistance appears across the
summing nodes in Over-The-Top operation and is due to
the common base input stage configuration. Its value is
easily derived from the specified input bias current flowing
into the op amp inputs and is equal to 2 k T/(q Ib)
(k-Boltzmann’s constant, T operating temperature,
Ib-operating input bias current of the amplifier in the
Over-The-Top region). And because the inputs are biased
proportional to absolute temperature, it is relatively
constant with temperature. The user may think this
effective resistance is relatively harmless because it
appears across the summing nodes which are forced

to 0V differential by feedback action of the amplifier.
However, depending on the configuration of the feedback
around the amplifier, this input resistance can boost noise
gain, lower overall amplifier loop gain and closed loop
bandwidth, raise output noise, with one benevolent effect
in increasing amplifier stability.
In the normal mode of operation (where V < VCM < V+
–1.5V), RIN is typically large compared to the value of the
input resistor used, and RIN can be ignored (refer to Figure 3).
In this case the noise gain is defined by the equation:
NOISE GAIN 1+
R
F
R
I
However, when the amplifier transitions into Over-The-Top
mode with the input common mode biased near or above
the the V+ supply, RIN should be considered. The noise
gain of the amplifier changes to:
NOISE GAIN =1+
R

RI|| RIN +RI||RF

Output
The output of the LT6015/LT6016/LT6017 can swing within
a Schottky diode drop (~0.4V) of the V+ supply, and within
5mV of the negative supply with no load. The output is
capable of sourcing and sinking approximately 25mA.
The LT6015/LT6016/LT6017 are internally compensated
to drive at least 200pF of capacitance under any output
loading conditions. For larger capacitive loads, a 0.22μF
capacitor in series with a 150Ω resistor between the out-
put and ground will compensate these amplifiers to drive
capacitive loads greater than 200pF.

Distortion
There are two main contributors of distortion in op amps:
output crossover distortion as the output transitions
from sourcing to sinking current and distortion caused
by nonlinear common mode rejection. If the op amp is
operating in an inverting configuration there is no com-
mon mode induced distortion. If the op amp is operating
in the noninverting configuration within the normal input
common mode range (V to V+ –1.5V) the CMRR is very
good, typically over 120dB. When the LT6015/LT6016/
LT6017 transitions input stages going from the normal
input stage to the Over-The-Top input stage or vice-versa,
there will be a significant degradation in linearity due to
the change in input circuitry.
Lower load resistance increases distortion due to a net
decrease in loop gain, and greater voltage swings internal
to the amp necessary to drive the load, but has no effect on
the input stage transition distortion. The lowest distortion
can be achieved with the LT6015/LT6016/LT6017 sourcing
in class-A operation in an inverting configuration, with the
input common mode biased mid-way between the supplies.
Power Dissipation Considerations
Because of the ability of the LT6015/LT6016/LT6017 to
operate on power supplies up to ±25V and to drive heavy
loads, there is a need to ensure the die junction tempera-
ture does not exceed 150°C. The LT6015 is housed in a
5-lead TSOT-23 package (JA = 250°C/W). The LT6016
is housed in an 8-lead MSOP package (JA = 273°C/W).
The LT6017 is housed in a 22 pin leadless DFN package
(DJC22, JA = 31.8°C/W).
In general, the die junction temperature (TJ) can be esti-
mated from the ambient temperature TA, and the device
power dissipation PD:
TJ = TA + PD JA
The power dissipation in the IC is a function of supply
voltage and load resistance. For a given supply voltage,
the worst-case power dissipation PD(MAX) occurs at the
maximum supply current with the output voltage at half
of either supply voltage (or the maximum swing is less
than one-half the supply voltage). PD(MAX) is given by:
PD(MAX) = (VS IS(MAX)) + (VS/2)2/RLOAD
Example: An LT6016 in a MSOP package mounted on a PC
board has a thermal resistance of 273°C/W. Operating on
±25V supplies with both amplifiers simultaneously driving
2.5kΩ loads, the worst-case IC power dissipation for the
given load occurs when driving 12.5VPEAK and is given by:
PD(MAX) = 2 50 0.6mA + 2 (12.5)2/2500 = 0.185W
With a thermal resistance of 273°C/W, the die temperature
will experience approximately a 50°C rise above ambient.
This implies the maximum ambient temperate the LT6016
should ever operate under the assumed conditions:
TA = 150°C – 50°C = 100°C
To operate to higher ambient temperatures, use two chan-
nels of the LT6017 quad which has lower thermal resistance
JA = 31.8°C/W, and an exposed pad which may be soldered
down to a copper plane (connected to V) to further lower
the thermal resistance below JA = 31.8°C/W.
