Instrumentation, Op Amps, Buffer Amps FAQ

How is the quiescent current adjusted?

An external resistor connected between V+ and the SHDN pin or between SHDNREF and ground sets the bias current.

What is the purpose of the COMP pin?

The COMP pin allows connection of an optional compensation capacitor to stabilize the amplifier when driving large capacitive loads.
