ISL28233FUZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FUZ-T7A is a dual precision operational amplifier from Renesas, featuring zero-drift architecture for high accuracy. It operates on a single supply voltage ranging from 1.65 V to 5.5 V or dual supplies of ±0.825 V to ±2.75 V. Key electrical parameters include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/µs, and an input offset voltage of 8 µV. The device draws 50 µA per channel with rail-to-rail input and output capabilities. Input bias current is 110 pA, while voltage noise density is 65 nV/√Hz. It is housed in an 8-MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' indicates tape and reel packaging when ordering. Confirm the 'FUZ' designation corresponds to the MSOP-8 package variant. Check current lifecycle status as some Intersil/Renesas legacy parts may have discontinuation notices. Ensure compatibility with your PCB footprint for the 8-lead micro-small outline package.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low offset drift and micro-power operation are required simultaneously. Compare against standard chopper amplifiers if higher bandwidth is needed. Consider the 8-MSOP package constraints for thermal management in dense layouts. Verify that the 400 kHz bandwidth meets the signal frequency requirements of the application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28233 family of dual precision amplifiers. It shares architectural similarities with other zero-drift op-amps but offers specific power and precision trade-offs defined by its internal chopping mechanism. The Renesas portfolio includes related single-channel and quad-channel variants for different pin count requirements.
