OPA349 - 1mA / Rail-to-Rail / CMOS OPERATIONAL AMPLIFIERS

Download the OPA349 datasheet PDF. This datasheet also covers the OPA349_Burr variant, as both devices belong to the same 1ma / rail-to-rail / cmos operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

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.
