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 of 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.The dual SGM8957-2 is available in Green SOIC-8,MSOP-8 and TDFN-3×3-8L packages.They are specified over-40℃to+125℃temperature range.
