ISL28233FRZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28233FRZ-T7 is a dual-channel micro-power operational amplifier from the Renesas ISL28233 series. It features zero-drift architecture with rail-to-rail input and output (RRIO) capabilities, designed for high-precision applications requiring low power consumption. The device operates within a supply voltage range of 1.8V to 6V, drawing only 50µA per channel. Key electrical specifications include a maximum input offset voltage of 6µV, an input bias current of 600pA, and a gain-bandwidth product of 400kHz. It is housed in an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift technology ensures minimal input offset voltage drift over temperature variations.
• Rail-to-rail input and output capability maximizes dynamic range in low-voltage systems.
• Micro-power operation provides ultra-low quiescent current for battery-powered devices.

Instrumentation, Op Amps, Buffer Amps Applications

• Precision sensor signal conditioning
• Medical instrumentation
• Industrial process control

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FRZ' against official Renesas documentation to confirm pinout compatibility and tape-and-reel specifications. Confirm RoHS compliance status and check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that demand high DC accuracy combined with low power consumption. It is suitable for replacing older chopper-stabilized amplifiers where lower noise and higher bandwidth are required. Ensure the application voltage stays within the 1.8V to 6V range to maintain specified performance metrics.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28233 family of dual precision operational amplifiers. It shares architectural similarities with other members like the ISL28233IUZ but differs in packaging and reel configuration. The series is characterized by its zero-drift design, making it distinct from standard CMOS or bipolar op-amps in the Renesas portfolio.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes such as the ISL28233FBZ-T7 or ISL28233IUZ-T7, ensuring package and electrical parameter alignment. Verify if alternative zero-drift amplifiers from other manufacturers meet the specific offset voltage and bias current requirements without compromising board space.
