The OPA333-Q1 CMOS operational amplifier uses a proprietary autocalibration technique to simultaneously provide verylow offset voltage (10 µV maximum) and near-zero drift over time and temperature. This miniature, high-precision, low-quiescent-current amplifier offers 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. The device can use single or dual supplies as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and is optimized for low-voltage single-supply operation.

The OPA333-Q1 device 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.
