Overview
The OPA4350UA/2K5 is a quad, single-supply, rail-to-rail, high-speed, low-noise operational amplifier produced by Texas Instruments. This component is part of the OPA350 series, which is optimized for low-voltage, single-supply operation. The OPA4350 is particularly suited for applications requiring high speed, low noise, and rail-to-rail input and output capabilities.
The device operates on a single supply as low as 2.5 V and features an input common-mode voltage range that extends 300 mV below ground and 300 mV above the positive supply. It is available in a space-saving SOIC (D) package with 14 pins.
