Overview
The OPA2333HD is a high-temperature MicroPower CMOS operational amplifier manufactured by Texas Instruments. This dual-channel amplifier is designed for precision applications, offering low offset voltage and near-zero drift over time and temperature. It is optimized for low-voltage, single-supply operation, making it ideal for battery-powered devices and other low-power applications. Its rail-to-rail output swing and high input impedance make it suitable for driving analog-to-digital converters (ADCs) and other signal processing tasks. The OPA2333HD is housed in an SOIC-8 package and is characterized by its low quiescent current and high common-mode rejection ratio (CMRR).
