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 100mV beyond the rails and rail-to-rail output that swings within 5mV of the rails. Single or dual supplies as low as +2.1V (±1.05V) 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.
