ISL28433FVZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28433FVZ is a quad micropower, chopper-stabilized operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 1.8 V to 6 V. Key electrical parameters include a gain-bandwidth product of 2 MHz, a slew rate of 0.2 V/µs, and an input offset voltage of 4 mV. The device draws 520 µA of operating current per channel and exhibits an input voltage noise density of 55 nV/√Hz. It is housed in a 14-TSSOP package and functions within a temperature range of -40°C to +125°C.
