Overview
The OPA340NA/250G4 is a single-supply, rail-to-rail operational amplifier produced by Texas Instruments. This device is optimized for low-voltage, single-supply operation and is part of the OPA340 series. It features rail-to-rail input and output, making it ideal for driving sampling analog-to-digital (A/D) converters, as well as general-purpose and audio applications. The OPA340NA/250G4 operates on a single supply as low as 2.5 V and has an input common-mode voltage range that extends 500 mV below ground and 500 mV above the positive supply.
