ISL21007DFB830Z-TK

Overview

The ISL21007DFB830Z-TK is a precision series voltage reference IC manufactured by Intersil (Renesas). It provides a fixed 3.0V output with an initial accuracy of +/-2.0mV. The device operates within an input voltage range of 3.2V to 5.5V and draws a maximum supply current of 150µA. It features very low noise, specified at 4.5µVP-P from 0.1Hz to 10Hz. The component is available in an 8-pin SOIC package and supports an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features ultra-low noise performance suitable for sensitive analog circuits
• Designed for low power consumption with minimal supply current draw

Applications

• Regulating output voltages for companion devices such as the ISL21007 and ISL21009
• Precision measurement systems requiring stable reference sources
• Data acquisition systems demanding low-noise voltage references

Procurement Notes

Verify the specific suffix '830Z' confirms the 3.0V output variant and tape-and-reel packaging format. Ensure compatibility with Renesas Electronics distribution channels following the corporate acquisition. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.0V reference with low noise is required. Compare against other ISL2100x family members if different voltage outputs or package types are needed. Consider the 150µA supply current constraint for battery-powered applications. Verify thermal performance within the -40°C to +125°C range for your specific environment.

Part Context

This part belongs to the ISL21007 family of precision voltage references from Intersil, now integrated into Renesas Electronics' portfolio. The manufacturer specializes in high-performance analog integrated circuits. This specific model represents a fixed-output variant designed for stability and low noise in industrial and communication equipment applications.

Replacement Considerations

Consult Renesas Product Legacy Documents for officially confirmed substitute part numbers. Direct replacements may require verification of pinout compatibility and electrical parameter equivalence. Generic equivalents should be evaluated against the original 4.5µVP-P noise specification and +/-2.0mV accuracy.
