General Description

The SGM8477-1/3 are low noise, high precision CMOS difference amplifiers, which are designed to support precision differential signal processing.

These devices can operate from 1.8V to 5.5V single supply or ±0.9V to ± 2.75V dual power supplies, and consume only 380μA quiescent current.

The supply current of SGM8477-3 is less than 0.5μA in shutdown mode, when external MCU controls EN pin to logic "low".
