SGM8956

GENERAL DESCRIPTION

The single SGM8955 and dual SGM8956 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. It is optimized for low voltage, single-supply operation.

The SGM8955/6 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 SGM8955 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages. The dual SGM8956 is available in Green SOIC-8, MSOP-8 and TDFN-3×3-8L packages. They are specified over -40 to +125 temperature range.
