Overview
The OPA2333AIDR is a dual-channel, low-power, CMOS operational amplifier produced by Texas Instruments. This device is part of the OPAx333 family, which is renowned for its high precision and low quiescent current. The OPA2333AIDR utilizes a proprietary auto-calibration technique to achieve very low offset voltage and near-zero drift over time and temperature, making it ideal for applications requiring high dc accuracy.
The amplifier is optimized for low-voltage, single-supply operation and can function with supply voltages ranging from 1.8 V to 5.5 V. It features rail-to-rail input and output stages, high-impedance inputs, and excellent common-mode rejection ratio (CMRR) without the crossover issues associated with traditional complementary input stages.
