Description

The MAX40100 is a low-power, zero-drift operational amplifier available in a space-saving, 6-bump, wafer-level package (WLP).

Designed for use in portable consumer, medical, and industrial applications, the MAX40100 features rail-to-rail CMOS inputs and outputs, a 1.5MHz GBW at just 66μA supply current, and 10µV (max) “zero-drift” input voltage offset over time and temperature.

The zero-drift feature of the MAX40100 reduces the high 1/f noise typically found in CMOS input operational amplifiers, making it useful for a wide variety of low-frequency measurement applications.

The MAX40100 is available in a space-saving, 1.1 x 0.76mm, 6-bump WLP, with 0.35mm bump pitch.

The MAX40100 is specified over the -40°C to +125°C extended automotive operating temperature range.
