DESCRIPTION/ORDERING INFORMATION

The OPA2333A CMOS operational amplifiers use a proprietary auto-calibration technique to simultaneously

provide very low offset voltage (10 mV 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 OPA2333A 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 OPA2333A is specified for operation from –40°C to 125°C.
