Introduction

AI Translation

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. The OPA349 can be operated with power supplies from 1.8V to 5.5V with little change in performance, ensuring continuing superior performance even in low battery situations. The OPA349 comes in miniature SOT23-5, SC70, and SO-8 surface-mount packages. The OPA2349 dual is available in SOT23-8, and SO-8 surface-mount packages. These tiny packages are ideal for use in high-density applications, such as PCMCIA cards, battery packs, and portable instruments. The OPA349 is specified for 0°C to +70°C. The OPA2349 is specified for -40°C to +70°C.
