The OPA2333-Q1 CMOS operational amplifiers use a proprietary autocalibration 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) can be used. This device is optimized for low-voltage single-supply operation.

The OPA2333-Q1 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 OPA2333-Q1 is specified for operation from –40°C to +125°C.
