ISL60002DIH310Z-TK

Overview

The ISL60002DIH310Z-TK is a precision series voltage reference utilizing Renesas Floating Gate Analog (FGA) technology. It provides a fixed output of 1.024V with an initial accuracy of ±0.24% and a temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V, drawing a typical supply current of 350nA. It supports source and sink currents up to 7mA and features ESD protection rated at 5.5kV (Human Body Model). Packaged in a standard SOT-23-3, it functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• High precision performance guaranteed by proprietary Floating Gate Analog (FGA) technology
• Ultra-low power consumption enabled by minimal 350nA typical supply current
• Robust electrostatic discharge protection capability rated at 5.5kV via Human Body Model

Applications

• High resolution low power data conversion systems
• Precision measurement instrumentation requiring stable reference voltages
• Battery powered devices necessitating extended operational life through low quiescent current

Procurement Notes

Verify the specific suffix Z-TK indicates tape and reel packaging configuration distinct from tube variants. Confirm RoHS compliance status as documentation may vary by production batch. Ensure input voltage remains within the specified 2.7V to 5.5V range to maintain guaranteed accuracy specifications. Check for post-assembly X-ray inspection warnings that may affect output voltage stability during manufacturing processes.

Selection Notes

Select this component when a sub-millivolt accuracy level is required alongside minimal power dissipation constraints. The 1.024V output suits applications interfacing directly with ADCs requiring specific reference levels. Consider the SOT-23-3 package size for space-constrained PCB layouts. Evaluate thermal management requirements given the low current draw, though heat generation is typically negligible under normal operating conditions.

Part Context

This part belongs to the ISL60002 FGA voltage reference family, designed to eliminate compromises between thermal stability and power consumption. Unlike traditional bandgap references, the floating gate architecture ensures long-term drift immunity. The DIH310 designation specifically identifies the 1.024V output variant with ±0.24% initial accuracy tolerance.

Replacement Considerations

Direct substitutes include other ISL60002 family members with compatible output voltages such as ISL60002DIH312 or ISL60002DIH325. Verify pinout compatibility and ensure the alternative device meets the same 350nA supply current and 20ppm/°C temperature coefficient requirements for equivalent system performance.
