High-Speed, Single-Supply, Rail-to-Rail Operational Amplifiers MicroAmplifier™ Series



The OPA4350 rail-to-rail CMOS operational amplifier is optimized for low voltage, single-supply operation. Rail-to-rail input/output, low noise, and high speed operation makes it ideal for driving sampling analog-to-digital (A/D) converters. It is also well suited for cell phone PA control loops and video processing (75-Ω drive capability) as well as audio and general purpose applications.

The OPA4350 operates on a single supply as low as 2.5 V with an input common-mode voltage range that extends 300 mV below ground and 300 mV above the positive supply.
