ISL60002DIH318Z-TK

Overview

The ISL60002DIH318Z-TK is a precision low-power Floating Gate Analog (FGA) voltage reference manufactured by Renesas/Intersil. It provides a fixed output voltage of 1.8 V with an initial accuracy of ±2.5 mV and a temperature coefficient of 20 ppm/°C. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing a typical supply current of 350 nA. It supports a maximum source and sink current of 7 mA and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it is designed for high-resolution data conversion systems.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for high precision and thermal stability
• Ultra-low power consumption with typical 350 nA supply current
• Guaranteed initial accuracy options including ±2.5 mV tolerance
• Low temperature coefficient of 20 ppm/°C for stable performance

Applications

• High resolution low power data conversion systems
• Portable battery operated instrumentation
• Medical equipment requiring precise voltage references
• Industrial process control systems

Procurement Notes

Verify the specific suffix Z-TK indicates cut tape or reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status through official datasheets. Ensure ESD handling precautions are followed due to sensitive internal circuitry. Check for post-assembly X-ray inspection warnings that may affect device output voltage stability during manufacturing processes.

Selection Notes

Select this component when a 1.8 V reference is required with ±2.5 mV initial accuracy. Compare against other ISL60002 variants for different voltage outputs like 1.25 V or 2.5 V if system requirements change. Consider the 7 mA drive capability for load requirements. Verify supply voltage constraints between 2.7 V and 5.5 V match the system rail availability.

Part Context

Part of the ISL60002 family of FGA voltage references from Renesas/Intersil. This series offers various fixed output voltages including 1.024 V, 1.2 V, 1.25 V, 1.8 V, 2.048 V, 2.5 V, 2.6 V, 3.0 V, and 3.3 V. All variants share similar low power characteristics and precision features suitable for analog signal chain applications.

Replacement Considerations

Direct substitutes include other ISL60002DIH3xx variants with different output voltages if electrical parameters allow adaptation. Verify pin compatibility in SOT-23-3 package. No alternative part numbers are explicitly confirmed as direct replacements in public documentation.
