Product Summary
The OPA2349UA 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 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’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 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.
