This resistor will isolate the feedback path (where excessive phase shift due to output capacitance can cause
instability) from the capacitive load. With a 10V supply, a 100Ω isolation resistor allows unlimited capacitive load
without oscillation compared to only 300pF without this resistor (A_V = +1).
• Higher supply voltage:
Operating the LMC8101 at higher supply voltages allows higher cap load tolerance. At 10V, the LMC8101's low
supply voltage cap load limit of 300pF improves to about 600pF (A_V = +1).
• Closed loop gain increase:
As with all Op Amps, the capacitive load tolerance of the LMC8101 increases with increasing closed loop gain. In
applications where the load is mostly capacitive and the resistive loading is light, stability increases when the
LMC8101 is operated at a closed loop gain larger than +1.
