General Description
The single MAX9910/MAX9911 and dual MAX9912/
MAX9913 operational amplifiers (op amps) feature a
maximized ratio of gain bandwidth (GBW) to supply
current and are ideal for battery-powered applications
such as portable instrumentation, portable medical
equipment, and wireless handsets. These CMOS op
amps feature an ultra-low input-bias current of 1pA, rail-
to-rail inputs and outputs, low supply current of 4µA,
and operate from a single 1.8V to 5.5V supply. For
additional power conservation, the MAX9911/MAX9913
feature a low-power shutdown mode that reduces sup-
ply current to 1nA, and puts the amplifiers’ outputs in a
high-impedance state. These devices are unity-gain
stable with a 200kHz GBW product.
The MAX9910 is available in a 5-pin SC70 package. The
MAX9911 is available in tiny 6-bump WLP and a 6-pin
SC70 packages. The MAX9912 is available in an 8-pin
SOT23 package, and the MAX9913 is available in a 10-
pin µMAX®package. All devices are specified over the
-40°C to +85°C extended operating temperature range.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
Featuring a maximized ratio of GBW to supply current,
low operating supply voltage, low input bias current,
and rail-to-rail inputs and outputs, the MAX9910–
MAX9913 are an excellent choice for precision or gen-
eral-purpose, low-current, low-voltage, battery-powered
applications. These CMOS devices consume an ultra-
low 4µA (typ) supply current and a 200µV (typ) offset
voltage. For additional power conservation, the
MAX9911/MAX9913 feature a low-power shutdown
mode that reduces supply current to 1nA (typ), and
puts the amplifiers’ output in a high-impedance state.
These devices are unity-gain stable with a 200kHz
GBW product, driving capacitive loads up to 30pF. The
capacitive load can be increased to 250pF when the
amplifier is configured for a 10V/V gain.
Rail-to-Rail Inputs and Outputs
All of the MAX9910–MAX9913 amplifiers have a parallel-
connected n- and p-channel differential input stage that
allows an input common-mode voltage range that
extends 100mV beyond the positive and negative sup-
ply rails, with excellent common-mode rejection.
The MAX9910–MAX9913 are capable of driving the out-
put to within 5mV of both supply rails with a 100k
load. These devices can drive a 5kload with swings
to within 60mV of the rails. Figure 1 shows the output
voltage swing of the MAX9910–MAX9913 configured as
a unity-gain buffer powered from a single 3V supply.
Low Input Bias Current
The MAX9910–MAX9913 feature ultra-low 1pA (typ)
input bias current. The variation in the input bias current
is minimal with changes in the input voltage due to very
high input impedance (in the order of 1G).
Applications Information
Driving Capacitive Loads
The MAX9910–MAX9913 amplifiers are unity-gain sta-
ble for loads up to 30pF. However, the capacitive load
can be increased to 250pF when the amplifier is config-
ured for a minimum gain of 10V/V. Applications that
require greater capacitive-drive capability should use
an isolation resistor between the output and the capaci-
tive load (Figure 2). Also, in unity-gain applications with
relatively small RL(approximately 5k), the capacitive
load can be increased up to 200pF.
Power-Supply Considerations
The MAX9910–MAX9913 are optimized for single 1.8V
to 5.5V supply operation. A high amplifier power-supply

rejection ratio of 95dB (typ) allows the devices to be
powered directly from a battery, simplifying design and
extending battery life.
Power-Up Settling Time
The MAX9910–MAX9913 typically require 5µs after
power-up. Supply settling time depends on the supply
voltage, the value of the bypass capacitor, the output
impedance of the incoming supply, and any lead resis-
tance or inductance between components. Op-amp
settling time depends primarily on the output voltage
and is slew-rate limited. Figure 3 shows the MAX991_ in
a noninverting voltage follower configuration with the
input held at midsupply. The output settles in approxi-
mately 18µs for VDD = 3V (see the
Typical Operating
Characteristics
for power-up settling time).
Shutdown Mode
The MAX9911/MAX9913 feature active-low shutdown
inputs. The MAX9911/MAX9913 enter shutdown in 2µs
(typ) and exit in 30µs (typ). The amplifiers’ outputs are
in a high-impedance state in shutdown mode. Drive
SHDN low to enter shutdown. Drive SHDN high to
enable the amplifier. The MAX9913 dual-amplifier fea-
tures separate shutdown inputs. Shut down both ampli-
fiers for the lowest quiescent current.
Power-Supply Bypassing and Layout
To minimize noise, bypass VDD with a 0.1µF capacitor
to ground, as close to the pin as possible.
Good layout techniques optimize performance
by decreasing the amount of stray capacitance and
inductance to the op amps’ inputs and outputs.
Minimize stray capacitance and inductance by placing
external components close to the IC.
