ISL28230FRZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FRZ-T7A is a dual-channel micro-power, zero-drift operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, making it suitable for low-voltage single-supply applications. The device operates within a supply voltage range of 1.8V to 5.5V or ±0.9V to ±2.75V in dual-supply configurations. Key electrical specifications include a maximum input offset voltage of 40µV, a typical quiescent current of 20µA per channel, and a gain-bandwidth product of 400kHz. It is housed in an 8-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift architecture ensures ultra-low input offset voltage and minimal drift over temperature variations.
• Rail-to-rail input and output stages maximize dynamic signal range in low-voltage systems.
• Micro-power consumption with a typical supply current of 20µA per channel extends battery life.
• High open-loop gain and common-mode rejection ratio provide precision signal amplification.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered handheld devices requiring extended operational life
• Precision sensor signal conditioning in industrial instrumentation
• Medical equipment such as infusion pumps and portable diagnostic tools
• Low-power data acquisition systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FRZ' against official Renesas documentation to confirm the exact package type (MSOP) and commercial temperature rating (0°C to 70°C). Confirm availability status as distribution channels may list obsolete or end-of-life variants. Ensure compatibility with PCB footprint dimensions for the 8-lead MSOP package during procurement planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption and high DC precision are required in space-constrained designs. Compare against the ISL28230FUZ variant if a wider industrial temperature range (-40°C to 125°C) is necessary. Verify that the 400kHz bandwidth meets the signal frequency requirements of the application circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family of zero-drift amplifiers, which includes single-channel (ISL28130) and quad-channel (ISL28430) versions. The family is designed for applications demanding high accuracy at very low power levels. The FRZ suffix specifically denotes the MSOP package option within this series.
