Active: In Production.

Description

The MAX9632 is a low-noise, precision, wide-band operational amplifier that can operate in a very wide +4.5V to +36V supply voltage range. The IC operates in dual (±18V) or single-supply mode (36V).

The exceptionally fast settling time and low distortion make the IC an excellent solution for precision acquisition systems. The rail-to-rail output swing maximizes the dynamic range when driving high-resolution 24-bit ΣΔ ADCs even with low supply voltages.

The IC achieves 55MHz of gain-bandwidth product and ultra-low 0.94nV/

input voltage noise with only 3.9mA of quiescent current.

The IC is offered in 8-pin SO, µMAX®, and TDFN packages and is rated for operation over the -40°C to +125°C temperature range.
