The OPA333A series of CMOS operational amplifiers uses a proprietary auto-calibration technique to simultaneously provide very low offset voltage (10 µV max) and near-zero drift over time and temperature. 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 50 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 OPA333A 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.

The OPA333A (single version) is available in the SC70-5 and SOT23-5 packages. The OPA2333A (dual version) is offered in the SO-8 package. All versions are specified for operation from -55°C to 125°C.
