ISL21060CFH641Z-TK

Overview

The ISL21060CFH641Z-TK is a low-power, high-precision voltage reference fabricated using Intersil's proprietary Floating Gate Analog (FGA) technology. It features a fixed output type with an input voltage range of 4.3V to 5.5V. The device exhibits a temperature coefficient of 25ppm/°C and operates within a junction temperature range of -40°C to 125°C. It carries a Moisture Sensitivity Level (MSL) rating of 1, indicating unlimited floor life for handling. The component is currently classified as obsolete.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for high precision
• Low power consumption design
• Fixed output voltage configuration
• Lead-free plastic packaging with matte tin finish

Applications

• Precision analog signal conditioning circuits
• High-resolution data acquisition systems
• Instrumentation requiring stable reference voltages

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify availability through authorized distributors or secondary market suppliers such as Rochester Electronics. Confirm that the specific suffix indicates the correct package and tape-and-reel configuration. Ensure compatibility with existing system designs before procurement due to end-of-life status.

Selection Notes

Select this part when a fixed, high-precision reference is required with low power constraints. The Floating Gate technology offers long-term stability advantages over traditional bandgap references. Consider the 4.3V to 5.5V input range and 25ppm/°C temperature coefficient against system requirements. Evaluate alternative active components if current supply chain support for obsolete parts is insufficient.

Part Context

The ISL21060 series belongs to Intersil's FGA voltage reference family, now under Renesas Electronics. These devices are designed for applications demanding superior accuracy and drift performance compared to standard references. The CFH641Z-TK designation specifies the fixed output variant in a specific surface-mount package with tape-and-reel packaging.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers must evaluate functional equivalents from other manufacturers or redesign around available inventory. No direct cross-reference is documented in the source material.
