ISL60002DIH330Z-TK

Overview

The ISL60002DIH330Z-TK is a precision series voltage reference IC manufactured by Renesas Electronics Corporation. It utilizes proprietary Floating Gate Analog (FGA) technology to deliver a fixed output voltage of 3.3V with an initial accuracy of ±1.0mV. The device operates within a supply voltage range of 3.2V to 5.5V and features an ultra-low supply current of 350nA typical. It exhibits a temperature coefficient of 20ppm/°C and supports a maximum sink/source current of 7mA. The component is housed in a space-saving SOT-23-3 package and is rated for operation from -40°C to +85°C.

Feature Summary

• Utilizes proprietary Floating Gate Analog (FGA) technology for high precision and stability
• Guarantees low initial accuracy of ±1.0mV with a temperature coefficient of 20ppm/°C
• Operates at ultra-low supply current of 350nA typical for efficient power management

Applications

• High resolution analog-to-digital converters (ADCs)
• High resolution digital-to-analog converters (DACs)
• Precision digital meters
• Bar code scanners

Procurement Notes

Verify the specific suffix Z-TK against official Renesas documentation to confirm tape and reel packaging specifications. Ensure compatibility with the required input voltage range of 3.2V to 5.5V for the 3.3V output variant. Confirm that post-assembly X-ray inspection is avoided or minimized, as it may cause permanent changes to the device output voltage. Cross-reference the RoHS compliance status with the latest manufacturer data sheets prior to procurement.

Selection Notes

Select this component when design requirements demand high DC accuracy combined with minimal power consumption. The FGA technology provides superior thermal stability compared to standard bandgap references. Consider the 7mA drive capability for direct loading applications without additional buffering. Verify that the SOT-23-3 footprint aligns with the PCB layout constraints and that the operating temperature range meets the environmental specifications of the target application.

Part Context

This part belongs to the ISL60002 family of precision low-power voltage references. The family offers various fixed output voltages including 1.024V, 1.2V, 1.25V, 1.8V, 2.048V, 2.5V, 2.6V, 3.0V, and 3.3V. Variants differ in accuracy grades and maximum operating temperatures, particularly the 3.3V version which supports up to +105°C in some configurations, though the DIH330Z-TK is specified for -40°C to +85°C.

Replacement Considerations

ISL60002CIH330Z-TK: Offers higher initial accuracy of ±2.5mV compared to the ±1.0mV of the DIH variant. ISL60002DAH333Z-TK: Provides a 3.3V output with extended operating temperature range up to +105°C and higher sink/source current capability of 20mA. Verify pinout compatibility and electrical parameter differences before substitution.
