ISL28233FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FBZ is a dual micropower, chopper-stabilized operational amplifier from Renesas Electronics. It features rail-to-rail inputs and outputs (RRIO) with a maximum input offset voltage of 6µV and low offset drift of 0.05µV/°C. The device operates on a single supply range of +1.65V to +6.0V or dual supplies of ±0.825V to ±3.0V. Key electrical parameters include a typical quiescent current of 18µA per amplifier, a gain-bandwidth product of 400kHz, and a slew rate of 0.2V/µs. Input bias current is typically 180pA, and the noise density is 65nV/√Hz.
