OPA2347UA

Instrumentation, Op Amps, Buffer Amps Overview

The UMW OPA2347UA is a dual-channel microPower operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.3V to 5.5V, with a typical quiescent current of 20µA per channel. The device offers a gain-bandwidth product of 350kHz and a slew rate of 0.17V/µs. Input offset voltage is specified at a maximum of 6mV, while the short-circuit current is ±17mA. It is housed in an SOP-8 package and supports operation across a temperature range of –55°C to +125°C.
