DESCRIPTION

The single SGM8957-1 and dual SGM8957-2 CMOS operational amplifiers provide very low offset voltage and zero-drift over time and temperature. The miniature, high-precision, low quiescent current amplifiers offer high-impedance inputs that have a wide input common mode range 100mV beyond the rails and rail-to-rail output that swings within 14mV of the rails. Single or dual supplies as low as +1.8V (±0.9V) and up to +5.5V (±2.75V) may be used. They are optimized for low voltage, single supply operation.

The SGM8957-1/-2 offer excellent CMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog-to-digital converters (ADCs) without degradation of differential linearity. The single SGM8957-1 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages.
