The single SGM8959-1 and dual SGM8959-2 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 and rail-to-rail output that swings within 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-supply operation.
The SGM8959-1/2 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 SGM8959-1 is available in Green SOT-23-5, SC70-5 and SOIC-8 packages. The dual SGM8959-2 is available in Green SOIC-8 and TDFN-3×3-8L packages. They are specified over -40℃ to +125℃ temperature range.
