ISL28233FRZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FRZ-T7A is a dual-channel, micro-power, zero-drift operational amplifier manufactured by Renesas Electronics. It features rail-to-rail input and output capabilities, making it suitable for low-voltage applications. Key electrical parameters include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/us, an input offset voltage of 8 uV, and an input bias current of 110 pA. The device operates on a single supply voltage ranging from 825 mV to 5.5 V or dual supplies up to ±2.75 V. It consumes 50 uA of quiescent current per channel and exhibits an input voltage noise density of 65 nV/sqrt Hz. The component is housed in an MSOP-8 package and functions within a temperature range of -40°C to +85°C.
