The OPA344NA/250G4 is a single-supply CMOS Operational Amplifier is optimized for low-voltage. High-speed operation make them ideal for driving sampling analogue-to-digital (A/D) converters. It is also well-suited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analogue (D/A) converters. The OPA340 series operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k load.
