ISL21007CFB820Z

Overview

The ISL21007CFB820Z is a precision series voltage reference IC from the FGA™ family, manufactured by Renesas Electronics Corporation (formerly Intersil). It provides a fixed output voltage of 2.048V with an initial accuracy tolerance of ±0.08%. The device operates within an input voltage range of 3.2V to 5.5V and draws a maximum supply current of 150µA. It features low noise performance of 4.5µVp-p in the 0.1Hz to 10Hz band and a temperature coefficient of 5ppm/°C. The component supports a maximum output current of 7mA and functions reliably across a junction temperature range of -40°C to 125°C.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerance for sensitive analog circuits.
• Exhibits ultra-low broadband noise characteristics suitable for high-resolution data acquisition systems.
• Offers stable thermal performance with a low temperature coefficient across extended industrial operating ranges.

Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision digital-to-analog converter (DAC) voltage references
• Medical instrumentation signal conditioning circuits
• Industrial process control measurement systems

Procurement Notes

Verify component authenticity through authorized Renesas distributors due to discontinued status. Confirm RoHS3 compliance and MSL level 1 handling requirements during storage. Check for product change notices regarding manufacturing site updates or labeling modifications issued between 2014 and 2025. Ensure replacement strategies account for end-of-life constraints in long-term production designs.

Selection Notes

Select this component when fixed 2.048V precision is required with minimal drift over temperature. Compare against adjustable references if system flexibility outweighs the need for inherent accuracy. Evaluate power consumption constraints against the 150µA supply current. Consider package availability in 8-SOIC format for surface mount assembly compatibility.

Part Context

Part of the Intersil FGA™ voltage reference family, now integrated into Renesas Electronics' portfolio following the 2016 acquisition. The ISL21007 series targets applications demanding superior stability and low noise compared to standard bandgap references. This specific variant represents a legacy part number within the broader precision analog signal processing lineup.

Replacement Considerations

Consult Renesas Product Legacy Documents for officially confirmed substitute part numbers. Verify pinout and electrical parameter compatibility before substitution. No direct public substitutes are listed in available documentation; engineering evaluation of equivalent Renesas voltage references is recommended.
