Applications

• High-resolution data acquisition systems
• Precision instrumentation amplifiers
• Calibration references for measurement equipment

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix indicates tape-and-reel packaging. Check for recent Product Change Notices regarding manufacturing site updates or labeling changes. Ensure compliance with RoHS3 standards as specified in official documentation.

Selection Notes

Select this component when a stable 1.25V reference is required with minimal drift over temperature. Compare against other FGA series variants if different output voltages or packaging options are needed. Ensure input voltage remains within the specified 3.2V to 5.5V range for proper regulation.

Part Context

This part belongs to the ISL21007 series of precision voltage references. It shares architectural similarities with other FGA™ series devices but offers specific electrical characteristics tailored for high-accuracy applications. The SOIC-8 package allows for surface-mount integration into compact PCB designs.

Replacement Considerations

Direct substitutes may include other ISL21007 variants with compatible pinouts and electrical specifications. Verify that alternative parts match the 1.25V output and 7mA current capability. Cross-reference thermal coefficients and noise specs to ensure equivalent performance.
