The MAX40108 is a low-power, high-precision operational amplifier (op amp) that operates with a power supply voltage as low as 0.9V.

Available in a space-saving, 1.22mmx 0.92mm, 6-bump wafer-level package (WLP) with a 0.4mm bump pitch, it is designed for use in portable, consumer, medical, and industrial applications.

The MAX40108 features rail-to-rail CMOS inputs and outputs, a 168kHz GBW consuming only 25.5µA (typ) supply current and 1µV (typ) zero-drift input offset voltage over time and temperature. The zero-drift feature 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 MAX40108 operates from a 0.9V to 3.6V power supply voltage and is specified over the -40°C to +125°C extended operating temperature range.

Applications

Fitness and Health (Smart Watch, Heart-Rate Monitor)

Product Details

The MAX40108 evaluation kit (EV kit) provides a proven design to evaluate the MAX40108 precision, low-noise, low-drift dual-operational amplifier in a 6-bump wafer- level package (WLP). The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components.

The EV kit comes with a MAX40108ANT+ installed.
