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, while consuming 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. They are designed to provide high performance for sensing high-side and low-side current accurately, such as single battery voltage.
The SGM8477-1/3 save external components by integrated matched resistors in differential applications. They have different versions for gains of 50 and 300.
