ISL28230CRZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230CRZ-T7 is a dual-channel micro-power operational amplifier from the Renesas ISL28x30 series, housed in an 8-DFN (3x3) package. It features a gain-bandwidth product of 400 kHz and a slew rate of 0.2 V/µs. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.75 V. Key electrical specifications include a maximum input offset voltage of 40 µV, input bias current of 250 pA, and typical supply current of 20 µA per channel. It supports rail-to-rail input and output capabilities.
