Status

Active: In Production.

Description

The MAX9633 is a low-noise, low-distortion operational amplifier that is optimized to drive ADCs for use in applications from DC to a few MHz. The MAX9633 features low noise (3nV/

at 1kHz and 3.5nV/

at 100Hz) and low distortion (130dB at 10kHz), making it suitable for industrial, medical, and test applications.

The exceptionally fast settling-time and low input offset voltage makes the IC an excellent solution to drive high-resolution 12-bit to 18-bit SAR ADCs.

The IC operates from a wide supply voltage range up to 36V with only 3.5mA of quiescent current per amplifier.

The IC is offered in an 8-pin, 3mm x 3mm TDFN package for operation over the -40°C to +125°C temperature range.
