OPA2333-HT - High Temperature 1.8-V Micropower CMOS Operational Amplifier Zero-Drift Series

The OPA2333 series of CMOS operational amplifiers uses a proprietary auto-calibration technique to simultaneously provide very low offset voltage and near-zero drift over time and temperature⁽¹⁾. These miniature, high-precision, low-quiescent-current amplifiers offer high-impedance inputs that have a common-mode range 100 mV beyond the rails, and rail-to-rail output that swings within 150 mV of the rails. Single or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V) may be used. They are optimized for low-voltage single-supply operation.

The OPA2333 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.
