ISL28430FVZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430FVZ is a quad-channel micro-power operational amplifier from the Renesas ISL28x30 series, optimized for low-voltage and low-power precision applications. It features a gain-bandwidth product of 400 kHz and a slew rate of 200 mV/us. The input offset voltage is typically 40 uV with an input bias current of 250 pA. Operating on a single supply from 1.8 V to 5.5 V or dual supplies from ±0.9 V to ±2.75 V, it draws 20 uA per channel. The device offers rail-to-rail input and output capabilities, a common-mode rejection ratio of 125 dB, and an input voltage noise density of 65 nV/sqrt Hz.
