The OPA2333HD is a high temperature MicroPower CMOS Operational Amplifier uses a proprietary auto-calibration technique to simultaneously provide very low offset voltage and near-zero drift over time and temperature. This miniature, high-precision, low-quiescent-current amplifier offers high-impedance inputs that has a common-mode range 100mV beyond the rails and rail-to-rail output that swings within 150mV of the rails. It is optimized for low-voltage single-supply operation. The OPA2333 family offers excellent common-mode rejection ratio (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.
