ISL21009DFB825Z

Overview

The ISL21009DFB825Z is a high-voltage input precision voltage reference from the FGA™ series, manufactured by Intersil (Renesas). It provides a fixed 2.5V output with an initial accuracy of ±0.16% and a temperature coefficient of 10 ppm/°C. The device operates within an extended temperature range of -40°C to +125°C and supports a maximum input voltage of 36V. It features low noise characteristics and is housed in an 8-lead SOIC package.

Feature Summary

• High-voltage input capability supporting up to 36V
• Precision output stability with ±0.16% initial accuracy
• Low noise performance suitable for sensitive analog circuits
• Extended industrial temperature operation range

Applications

• Industrial control systems requiring stable reference voltages

Procurement Notes

Verify the specific suffix (DFB) against official Renesas documentation to confirm pinout and electrical tolerances. Ensure the source document explicitly lists the 2.5V output and 10 ppm/°C drift rate. Cross-reference the manufacturer designation as Intersil or Renesas Electronics Corporation to avoid counterfeit components.

Selection Notes

Select this component when a fixed 2.5V reference is required with high initial accuracy and low noise. It is suitable for applications demanding high input voltage tolerance up to 36V. Consider the 8-SOIC package constraints and the specified temperature range for environmental compatibility.
