ISL28233FRZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FRZ is a dual micropower, chopper-stabilized operational amplifier from Renesas Electronics. It features rail-to-rail input and output capabilities, optimized for single supply operation from 1.65V to 6.0V or dual supplies of ±0.825V to ±3.0V. Key electrical parameters include a maximum input offset voltage of 6µV, typical quiescent current of 18µA per amplifier, and a gain-bandwidth product of 400kHz. The device operates over an extended temperature range of -40°C to +125°C and is housed in an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Chopper-stabilized architecture ensures low input offset voltage and minimal drift.
• Rail-to-rail input and output stages maximize dynamic signal range.
• Micropower consumption with typical 18µA quiescent current per channel.

Instrumentation, Op Amps, Buffer Amps Applications

• Bidirectional current sensing
• Precision temperature measurement
• Electronic weighing scales
• Strain gauge sensor interfaces

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FRZ' against official Renesas documentation to confirm the exact package type (SOIC) and tape/reel quantity specifications. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm availability status as distribution channels may vary for this specific part number variant.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low offset voltage and drift are critical alongside low power consumption. The chopper-stabilized design eliminates 1/f noise, making it suitable for DC precision applications. Verify that the 400kHz bandwidth meets the system's speed requirements and that the 18µA current draw aligns with battery life constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the ISL28233 family of zero-drift amplifiers. It shares architectural similarities with other members like the ISL28233IUZ but differs in packaging and specific ordering suffixes. The family is designed for high-precision analog front ends requiring stability over temperature and time without external trimming.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements must match the dual-channel configuration, chopper-stabilized topology, and SOIC-8 package. Verify pinout compatibility and electrical parameter equivalence, specifically offset voltage and supply voltage range, before substitution.
