ISL21007CFB825Z-TK

Overview

The ISL21007CFB825Z-TK is a series voltage reference IC manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.08%. The device operates within an input voltage range of 3.2V to 5.5V and delivers a maximum output current of 5 mA. Key performance specifications include a temperature coefficient of 5 ppm/°C and low noise characteristics, measuring 4.5 µVp-p in the 0.1Hz to 10Hz frequency band. The component is designed for surface mount installation in an 8-SOIC package.

Feature Summary

• Provides stable precision voltage referencing with high initial accuracy
• Features low-noise performance suitable for sensitive analog circuits
• Operates reliably across extended industrial temperature ranges

Applications

• Data acquisition systems requiring precise voltage references
• High-resolution analog-to-digital converter (ADC) biasing
• Precision measurement instrumentation
• Industrial process control equipment

Procurement Notes

Verify that the specific suffix -TK indicates tape-and-reel packaging rather than tube packaging when sourcing this variant. Confirm RoHS compliance status and check for any recent product change notices regarding manufacturing sites or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.5V reference with tight initial tolerance is required. Ensure the application input voltage remains within the specified 3.2V to 5.5V operational window. Consider the 8-SOIC package dimensions for PCB layout constraints and verify that the 5 mA output current capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the ISL21007 family of series voltage references from Renesas Electronics. The family offers various fixed output voltages including 2.5V, 3.0V, and others, all sharing similar low-noise and high-precision characteristics. The ISL21007 series is designed to replace older Intersil precision reference designs, maintaining compatibility with established high-performance analog system architectures.

Replacement Considerations

The datasheet identifies ISL21007DFB830Z as an obsolete recommended replacement for certain variants in the series. Verify pinout and electrical parameter compatibility before substituting other parts in the ISL21007 family.
