Overview
The OPA340UA/2K5G4 is a single-supply, rail-to-rail operational amplifier from Texas Instruments. This device is part of the OPA340 series, which is optimized for low-voltage, single-supply operation. The OPA340 series is fabricated on a state-of-the-art, 0.6-micron CMOS process and is unity-gain stable, making it suitable for a wide range of general-purpose applications. The rail-to-rail input and output capabilities, along with high-speed operation, make these amplifiers ideal for driving sampling analog-to-digital (A/D) converters and for use in audio applications and I/V conversion at the output of digital-to-analog (D/A) converters.
