TI OPA2333AIDGKR

The OPA333 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 OPA333 family offers excellent 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 OPA333 (single version) is available in the SC70 - 5, SOT23 - 5, and SO - 8 packages. The OPA2333 (dual version) is offered in DFN - 8 (3 mm × 3 mm), MSOP - 8, and SO - 8 packages. All versions are specified for operation from -40°C to +125°C
