ISL60002BIH325Z-TK

Overview

The ISL60002BIH325Z-TK is a precision series voltage reference manufactured by Renesas Electronics Corporation. It utilizes proprietary Floating Gate Analog (FGA) technology to deliver high accuracy and stability. The device provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of ±1.0 mV. It operates within a supply voltage range of 2.7 V to 5.5 V and features a low temperature coefficient of 20 ppm/°C. The component supports a maximum source and sink current of 7 mA while maintaining ultra-low supply current consumption. It is housed in a compact SOT-23-3 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Utilizes Renesas proprietary Floating Gate Analog (FGA) technology for high precision and long-term stability without requiring external components.
• Provides guaranteed absolute initial accuracy as low as ±1.0 mV, eliminating the need for post-assembly trimming or calibration.
• Features ultra-low supply current consumption typical of 350 nA, enabling efficient power management in battery-operated systems.
• Includes robust ESD protection rated at 5.5 kV (human body model) to enhance reliability during handling and assembly.

Applications

• High-resolution, low-power data conversion systems
• Portable instrumentation requiring precise analog references
• Battery-powered measurement devices
• Medical equipment requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official datasheets, as historical variants may differ. Ensure design reviews account for potential output voltage shifts if post-assembly X-ray inspection is required by your manufacturing process. Cross-reference the manufacturer part number directly with Renesas documentation to avoid confusion with obsolete non-Z suffixes.

Selection Notes

Select this component when a fixed 2.5 V reference with ±1.0 mV accuracy is required in a small SOT-23-3 footprint. It is suitable for applications demanding low quiescent current and high thermal stability over the industrial temperature range. Consider alternative output voltages from the ISL60002 family if system requirements differ from 2.5 V. Verify input voltage constraints against the 2.7 V minimum requirement for proper regulation.

Part Context

This part belongs to the ISL60002 FGA voltage reference family, which integrates floating gate memory cells to store reference values permanently. The family offers various output voltages including 1.024 V, 1.2 V, 1.25 V, 1.8 V, 2.048 V, 2.6 V, 3.0 V, and 3.3 V. The BI suffix typically denotes the ±1.0 mV accuracy grade within this series.

Replacement Considerations

Direct substitutes include other ISL60002BIH3xx variants with different output voltages but identical pinouts and accuracy grades. Non-Z suffix versions (e.g., ISL60002BIH325Z-TK vs older ISL60002BIH325) may have packaging differences; verify RoHS compliance and lead-free status before substitution.
