Overview
The OPA2333AQDGKRQ1 is a high-precision, micropower, CMOS operational amplifier designed by Texas Instruments. This device is part of the zero-drift series and is optimized for low-voltage, single-supply operation. It features a proprietary autocalibration technique that provides very low offset voltage and near-zero drift over time and temperature. The OPA2333-Q1 is unity-gain stable, free from output phase reversal, and offers rail-to-rail input and output stages. It is AEC qualified for automotive applications and operates over a temperature range of –40°C to +125°C.
