OPA2241UA

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2241UA is a dual-channel, voltage-feedback operational amplifier from the microPOWER family. It operates on single supplies from 2.7V to 36V or dual supplies from ±1.35V to ±18V. Key electrical parameters include a maximum input offset voltage of ±250μV, a gain-bandwidth product of 35kHz, and a quiescent current of 25μA per channel. The device features rail-to-rail output swing within 50mV and high common-mode rejection ratios.
