Instrumentation, Op Amps, Buffer Amps FAQ

How does the LT1359 handle capacitive loads?

The LT1359 is stable with any capacitive load due to an internal RC network that adds phase margin, preventing oscillation even under heavy capacitive loading conditions.

What is the input bias current characteristic?

The inputs utilize complementary NPN and PNP emitter followers that provide first-order bias current cancellation, resulting in low input bias current and well-controlled offset current.
