MAX40100

Precision, Low-Power, and Low-Noise Op Amp with RRIO

Save Power and Board Space—1.5MHz GBW at Just 66µA Supply Current in a Space-Saving 6-Bump WLP


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.
