General Notes: Devices are ESD protected; however, handling precautions are recommended. All limits guaranteed by testing on statistical analysis.
Note 1.
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when
operating the device outside its recommended operating ratings.
Note 2.
I/O Pin Voltage is any external voltage to which an input or output is referenced.
Note 3.
The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max); the junction-to-ambient thermal
resistance, θJA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using:
PD = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
Note 4.
Thermal resistance, θJA, applies to a part soldered on a printed-circuit board.
Note 5.
Human body model, 1.5k in series with 100pF.
Note 6.
Common-mode performance tends to follow the typical value. Minimum value limits reflect performance only near the supply rails.
Note 7.
Continuous short circuit may exceed absolute maximum TJ under some conditions.
Note 8.
Shorting OUT to V+ when V+ > 12V may damage the device.
Note 9.
RL connected to 5.0V. Sourcing: 5V ≤ VOUT ≤ 12V. Sinking: 2.5V ≤ VOUT ≤ 5V.
Note 10. Device connected as a voltage follower with a 12V step input. The value is the positive or negative slew rate, whichever is slower.

Driving Capacitive Loads
ROUT =
Input Common-Mode Voltage
Some amplifiers exhibit undesirable or unpredictable performance when the inputs are driven beyond the common-mode
voltage range, for example, phase inversion of the output
signal. The LMC7101 tolerates input overdrive by at least
200mV beyond either rail without producing phase inversion.
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 LMC7101 can typically
drive a 100pF capacitive load connected directly to the output
when configured as a unity-gain amplifier.
If the absolute maximum input voltage (700mV beyond either
rail) is exceeded, the input current should be limited to ±5mA
maximum to prevent reducing reliability. A 10kΩ 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 1.
RIN
Using Large-Value Feedback Resistors
A large-value feedback resistor (> 500kΩ) 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 fedback 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.
VOUT
Figure 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:

Output Voltage Swing
Sink and source output resistances of the LMC7101 are
equal. Maximum output voltage swing is determined by the
load and the approximate output resistance. The output
resistance is:
ROUT =
RIN × CIN ≤ RFB × CFB

VOUT
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
Electrical Characteristics DC (5V) table, the typical output
high voltage using a 2kΩ load (connected to V+/2) is 4.989V,
which produces an ILOAD of

Figure 2. Cancelling Feedback Phase Lag
Since 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.

Voltage drop in the amplifier output stage is:
VDROP = 5.0V – 4.989V
VDROP = 0.011V
Because of output stage symmetry, the corresponding typical
output low voltage (0.011V) also equals VDROP. Then:
