ISL28433FBZ-T7A

Overview

The ISL28433FBZ-T7A is a quad micropower, chopper-stabilized operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, optimized for single and dual supply voltages. The device operates within a single supply voltage range of 1.8V to 6V, with a maximum supply voltage (VS Max) of 6V. Key electrical parameters include a slew rate of 0.2 V/µs and an output voltage swing up to 4.9V. The component does not include thermal shutdown protection. This quad configuration integrates four independent channels within a single package.

Feature Summary

• Chopper stabilization technology minimizes offset voltage and drift for high precision.
• Rail-to-rail input and output operation maximizes dynamic range.
• Micropower consumption design optimizes energy efficiency in portable applications.

Applications

• Battery-powered instrumentation systems
• Precision sensor signal conditioning
• Medical diagnostic equipment

Procurement Notes

Verify the specific suffix T7A indicates the tape-and-reel packaging format when ordering. Confirm that the quad channel variant matches the system requirements, as the ISL28233 offers a dual-channel alternative. Ensure the 6V maximum supply rating aligns with the target circuit design constraints before finalizing procurement.

Selection Notes

Select this component when low power consumption and high DC accuracy are required simultaneously. The chopper-stabilized architecture is suitable for applications sensitive to offset voltage drift over temperature. Consider the quad topology if space savings are critical compared to using multiple dual amplifiers.

Part Context

This part belongs to the ISL28x33 family of micropower operational amplifiers from Renesas. The family includes the ISL28233 (dual) and ISL28433 (quad) variants. These devices share identical electrical characteristics but differ in channel count, allowing designers to choose based on integration needs without compromising performance specifications.

Replacement Considerations

The ISL28233 serves as a functional substitute if only two channels are required, offering identical electrical performance in a dual package. Verify pin compatibility and package dimensions when transitioning between the quad and dual variants to ensure board layout adjustments are unnecessary.
