Product Summary

The OPA2349UA/2K5 is an ultra-low power operational amplifier that provides 70kHz bandwidth with only 1µA quiescent current. The rail-to-rail input and output amplifier OPA2349UA/2K5 is specifically designed for battery powered applications. Unlike some micropower op amps, these parts are unity-gain stable and require no external compensation. The OPA2349UA/2K5’s low input bias current allows the use of large source and feedback resistors. The input common-mode voltage range extends 200mV beyond the power supply rails and the output swings to within 150mV of the rails, maintaining wide dynamic range. The applications of the OPA2349UA/2K5 include battery packs and power supplies, portable phones/ pagers/ cameras, solar-powered systems, smoke/ gas/ fire detection systems, remote sensors, pcmcia cards, driving a/d converters and micropower filters.
