More Information
The OPA349 and OPA2349 are ultra-low power operational amplifiers that provide 70kHz bandwidth with only 1µA quiescent current. These rail-to-rail input and output amplifiers are specifically designed for battery-powered applications. The input common-mode voltage range extends 200mV beyond the power-supply rails and the output swings to within 350mV of the rails, maintaining wide dynamic range. Unlike some micropower op amps, these parts are unity-gain stable and require no external compensation to achieve wide bandwidth. The OPA349 features a low input bias current that allows the use of large source and feedback resistors.
