OPA132U

Instrumentation, Op Amps, Buffer Amps Overview

The OPA132U is a single-channel high-speed JFET-input operational amplifier manufactured by Texas Instruments. It features an 8 MHz gain-bandwidth product and a 20 V/us slew rate, housed in an SOIC-8 surface-mount package. The device operates on supply voltages ranging from 5 V to 36 V with a quiescent current of 4 mA per channel. Key electrical specifications include a maximum input offset voltage of 200 uV, input bias current of 50 pA, and output short-circuit current capability of 40 mA. It supports rail-to-rail input/output operation within the specified temperature range.
