MAXIM INTEGRATED MAX40108 Low-Power Precision Operational Amplifier

Maxim Integrated’s MAX40108 is a low-power precision op amp that is well suited for low-frequency measurements in wearable, home medical, fitness and health, and industrial IoT applications. 

The MAX40108 can operate from a 0.9V to 3.6V supply. It consumes just 25.5µA of quiescent current while active and drops to 320nA in shutdown mode, making it ideal in low-voltage, battery-powered devices. It features rail-to-rail CMOS inputs and outputs, with very low input bias current and 1µV zero-drift input offset voltage. The zero-drift design greatly reduces 1/f noise compared to conventional CMOS op amps, making the MAX40108 ideal for sensors operating at low voltage and frequency. 

The MAX40108 has a 168kHz gain bandwidth product and internal EMI rejection. It’s offered in tiny WLP or TDFN packages and can operate from -40°C to +125°C.
