SGM8954-1

GENERAL DESCRIPTION

The single SGM8954-1 and dual SGM8954-2 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 5.5mV 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 or dual supply operation.

The SGM8954-1/2 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 SGM8954-1 is available in Green SOT-23-5, SOIC-8 and UTDFN-1.6×1.6-6L packages. The dual SGM8954-2 is available in Green SOIC-8, MSOP-8 and TDFN-2×2-8L packages. They are specified over the extended industrial temperature range (-40 to +125).
