ISL60002DIH320Z

Overview

The ISL60002DIH320Z-TK is a precision voltage reference from the ISL60002 series, manufactured by Renesas Electronics (formerly Intersil). It utilizes proprietary Floating Gate Analog (FGA) technology to deliver a fixed output voltage of 2.048 V with an initial accuracy of ±0.24%. The device operates within a supply voltage range up to 6.5 V and supports a maximum shunt current of 7 mA. It features a low temperature coefficient of 20 PPM/°C and functions reliably across an extended industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it is designed for low-power applications.

Feature Summary

• Utilizes proprietary Floating Gate Analog (FGA) technology for high precision and stability.
• Provides guaranteed initial accuracy options including ±1.0 mV, ±2.5 mV, and ±5.0 mV variants.
• Features ultra-low supply current consumption of typically 350 nA.
• Includes ESD protection rated at 5.5 kV human body model.

Applications

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

Procurement Notes

Verify the specific suffix (e.g., -TK vs -T7A) to confirm packaging type such as cut tape or reel. Confirm RoHS compliance status through official datasheets. Ensure input voltage does not exceed the 6.5 V maximum rating. Check for post-assembly X-ray inspection warnings that may affect output voltage stability.

Selection Notes

Select this component when a stable 2.048 V reference is required with tight initial accuracy tolerances. Consider the 7 mA sink/source capability for driving moderate loads. Compare against other ISL60002 variants if different output voltages or higher current capabilities (20 mA for 3.3V versions) are needed. Verify package availability in SOT-23-3.

Part Context

This part belongs to the ISL60002 family of Floating Gate Analog voltage references. The family offers various output voltages including 1.024 V, 1.25 V, 2.048 V, 2.5 V, and 3.3 V. The 'D' in the part number typically denotes specific accuracy grades, while 'H320' indicates the 2.048 V output. The manufacturer transitioned from Intersil to Renesas Electronics.

Replacement Considerations

Other parts in the ISL60002 family share similar FGA technology and pinouts. Variants like ISL60002BIH325Z-TK offer 2.5 V output. Direct substitutes must match the SOT-23-3 package and 2.048 V output. Verify thermal coefficient and accuracy specifications against original requirements.
