ISL28230CRZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230CRZ-T7A is a dual-channel micro-power, zero-drift operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, making it suitable for low-voltage single-supply applications. The device operates within a supply voltage range of 1.8 V to 5.5 V. Key electrical specifications include a maximum input offset voltage of 5 µV, an input bias current of 250 pA, and a typical supply current of 20 µA per channel. The gain-bandwidth product is 400 kHz with a slew rate of 0.2 V/µs. It is housed in an 8-DFN (3x3) package with exposed pad and supports commercial temperature operation from 0°C to 70°C.
