The SGM8477-1/3 CMOS difference amplifiers provide very low offset voltage, low noise and zero-drift over time and temperature for precision differential signal processing.

The miniature, high-precision, low quiescent current amplifiers offer rail-to-rail input and output. Single or dual supplies as low as +1.8V (±0.9V) and up to +5.5V (±2.75V) may be used. It is optimized for low voltage operation.

SGM8477-1/3 are high performance amplifiers for accurate high-side and low-side current sensing, such as single battery voltage. SGM8477-3 can enter into shutdown status (IQ < 0.5μA) when EN pin is logical “low”, controlled by the external MCU.

Integrated matched resistors for differential application save external components. The SGM8477-1/3 have different versions for gains of 50 and 300.
