General Description
The MIC7300 is a high-performance CMOS
operational amplifier featuring rail-to-rail input and
output with strong output drive capability. It is able to
source and sink in excess of 80 mA into large
capacitive loads.
The input common-mode range extends beyond the
rails by 300 mV, and the output voltage typically swings
to within 150 V of both rails when driving a 100 k
load.
The amplifier operates from 2.2V to 10V and is fully
specified at 2.2V, 3V, 5V, and 10V. Gain bandwidth and
slew rate are 500 kHz and 0.5 V/s, respectively.
The MIC7300 is available in the IttyBitty SOT-23-5
package for space-conscious circuits and in
high-power MM8 8-lead MSOP for improved heat
dissipation in higher power applications.

4.0 APPLICATION INFORMATION
4.1 Input Common-Mode Voltage
The MIC7300 tolerates input overdrive by at least
300 mV beyond either rail without producing phase
inversion.
If the absolute maximum input voltage is exceeded, the
input current should be limited to ±5 mA maximum to
prevent reducing reliability. A 10 k series input
resistor, used as a current limiter, will protect the input
structure from voltages as large as 50V above the
supply or below ground. See Figure 4-1.

4.2 Output Voltage Swing
Sink and source output resistances of the MIC7300 are
equal. Maximum output voltage swing is determined by
the load and the approximate output resistance. The
output resistance is shown in Equation 4-1.
EQUATION 4-1:
ROUT
VDROP
ILOAD
------------------=
VDROP is the voltage dropped within the amplifier
output stage. VDROP and ILOAD can be determined from
the VO (output swing) portion of the appropriate
Electrical Characteristics table. ILOAD is equal to the
typical output high voltage minus V+/2 and divided by
RLOAD. For example, using the 5V table, the typical
output high voltage using a 2 k load (connected to
V+/2) is 4.985V, which produces an ILOAD of:

Voltage drop in the amplifier output stage is:
EQUATION 4-3:

Because of output stage symmetry, the corresponding
typical output low voltage (0.015V) also equals VDROP.

4.3 Power Dissipation
The MIC7300 output drive capability requires
considering power dissipation. If the load impedance is
low, it is possible to damage the device by exceeding
the maximum junction temperature rating.
On-chip power consists of two components: supply
power and output stage power. Supply power (PS) is
the product of he supply voltage (VS = VV+ – VV–) and
supply current (IS).
Output stage power (PO) is the product of the output
stage voltage drop (VDROP) and the output (load)
current (IOUT). Total on-chip power dissipation is:
EQUATION 4-5:
PDPSPO
+=
Where:
PD = Total on-chip power
PS = Supply power dissipation
PO = Output power dissipation
EQUATION 4-6:
PDVSISVDROPIOUT
+=
Where:
VS = VV+ – VV–
IS = Power supply current
VDROP = VV+ – VOUT (sourcing current)
VDROP = VOUT – VV– (sinking current)
Equation 4-5 and 4-6 address only steady state (DC)
conditions. For non-DC conditions the user must
estimate power dissipation based on the RMS value of
the signal.
The task is one of determining the allowable on-chip
power dissipation for operation at a given ambient
temperature and power supply voltage. From this
MIC7300
DS20006305A-page 12 2020 Microchip Technology Inc.
determination, one may calculate the maximum
allowable power dissipation and, after subtracting PS,
determine the maximum allowable load current, which
in turn can be used to determine the minimum load
impedance that may safely be driven. The calculation
is summarized below.

4.4 Driving Capacitive Loads
Driving a capacitive load introduces phase-lag into the
output signal, and this in turn reduces op-amp system
phase margin. The application that is least forgiving of
reduced phase margin is a unity gain amplifier. The
MIC7300 can typically drive a 2500 pF capacitive load
connected directly to the output when configured as a
unity-gain amplifier and powered with a 2.2V supply. At
10V operation the circuit typically drives 6000 pF.
Phase margin is typically 40 degrees.
4.5 Using Large-Value Feedback
Resistors
A large-value feedback resistor (> 500 k) can reduce
the phase margin of a system. This occurs when the
feedback resistor acts in conjunction with input
capacitance to create phase lag in the feedback signal.
Input capacitance is usually a combination of input
circuit components and other parasitic capacitance,
such as amplifier input capacitance and stray printed
circuit board capacitance.
Figure 4-2 illustrates a method of compensating phase
lag caused by using a large-value feedback resistor.
Feedback capacitor CFB introduces sufficient phase
lead to overcome the phase lag caused by feedback
resistor RFB and input capacitance CIN. The value of
CFB is determined by first estimating CIN and then
applying the following formula shown in Equation 4-8:

FIGURE 4-2: Canceling Feedback Phase
Lag.
Because a significant percentage of CIN may be
caused by board layout, it is important to note that the
correct value of CFB may change when changing from
a breadboard to the final circuit layout.

Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
