Instrumentation, Op Amps, Buffer Amps FAQ

How does the MAX44290 eliminate crossover distortion?

It utilizes an internal charge pump that creates a voltage rail 1V above VDD to power the PMOS input differential pair, removing the crossover distortion found in standard CMOS structures.

What is the recovery time when exiting shutdown mode?

The device recovers from shutdown in less than 30µs without requiring self-calibration, retaining its power-up trim settings.
