SGM8955/SGM8956 1.8V, Micro-Power CMOS Zero-Drift Operational Amplifiers
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. They are optimized for low voltage, single-supply operation.
The SGM8955/6 offer excellent CMRR without the crossover associated with traditional complementary input stages.
