## DESCRIPTION/ORDERING INFORMATION
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.
