SGM8477-1/SGM8477-3 1.8V to 5.5V, Low Noise, Zero-Drift Difference Amplifiers 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". The SGM8477-1/3 feature low noise, a 10μV maximum input offset voltage and zero-drift over time and temperature. These devices are suitable in low voltage and low power systems. They support rail-to-rail input and output operation. Meanwhile, the SGM8477-1/3 fit in tiny packages.
