Overview
The OPA2333AIDRBR is a dual-channel, high-precision operational amplifier manufactured by Texas Instruments. It is part of the OPAx333 series, which utilizes a proprietary auto-calibration technique to achieve very low offset voltage and near-zero drift over time and temperature. This device is designed for low-voltage, single-supply operation and is optimized for applications requiring high precision and low power consumption.
