ISL21009DFB862Z-TK

Overview

The ISL21009DFB862Z-TK is a high-precision, low-noise FGA™ series voltage reference IC manufactured by Intersil (Renesas). It provides a fixed output voltage of 6.23V with an initial accuracy tolerance of ±0.16%. The device operates within an input voltage range of 3.5V to 16.5V and draws a supply current of 180µA. It features a maximum temperature coefficient of 10ppm/°C and supports a maximum load current of 7mA. Packaged in an 8-SOIC surface-mount case, it is designed for applications requiring stable reference voltages.

Feature Summary

Procurement Notes

Verify the specific suffix TK against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as per the latest datasheet revision. Check for any product change notices regarding wafer fabrication site updates or marking changes that may affect part identification. Ensure the source document explicitly lists this part number to avoid substitution errors with similar ISL21009 variants.

Selection Notes

Select this component when a fixed 6.23V reference is required with tight initial accuracy of ±0.16%. It is suitable for designs needing low noise and a temperature coefficient of 10ppm/°C. Consider the 8-SOIC package for surface-mount assembly. Verify that the input voltage remains within the 3.5V to 16.5V range and that the load current does not exceed 7mA during operation.

Part Context

This part belongs to the ISL21009 family of high-voltage input precision voltage references from Intersil, now part of Renesas Electronics. The family utilizes FGA™ technology to achieve low noise and high stability. The ISL21009DFB862Z-TK specifically offers a 6.23V output, distinguishing it from other variants in the series that provide different fixed voltage levels such as 2.5V or 4.096V.
