Overview
The OPA2333AIDGKT is a dual-channel, micropower, zero-drift CMOS operational amplifier produced by Texas Instruments. This device is part of the OPAx333 series, which utilizes a proprietary auto-calibration technique to provide very low offset voltage and near-zero drift over time and temperature. The OPA2333AIDGKT is optimized for low-voltage, single-supply operation and is available in an 8-pin VSSOP package.
These amplifiers are designed for high-precision applications, offering high-impedance inputs with a common-mode range 100 mV beyond the supply rails and rail-to-rail output that swings within 50 mV of the rails. They are suitable for a wide range of applications requiring low power consumption and high accuracy.
