ISL60002BIH326Z

Overview

The ISL60002BIH326Z is a precision voltage reference from the Renesas/Intersil ISL60002 family, utilizing proprietary Floating Gate Analog (FGA) technology. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±1.0 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 and features ultra-low supply current of 350 nA typical. It supports source and sink currents up to 7 mA and functions in temperatures from -40°C to +85°C. Packaged in a space-saving SOT-23-3, it is designed for low-power data conversion systems.

Feature Summary

• Utilizes proprietary Floating Gate Analog (FGA) technology for high precision and stability
• Guarantees initial accuracy as low as ±1.0 mV with 20 ppm/°C temperature coefficient
• Operates at ultra-low supply current of 350 nA typical for minimal power consumption
• Provides robust load regulation with 7 mA source and sink capability

Applications

• High resolution, low power data conversion systems
• Portable battery-powered instrumentation
• Precision measurement equipment requiring stable reference voltages
• Medical devices with strict power and accuracy constraints

Procurement Notes

Verify the specific suffix codes against official Renesas documentation to confirm exact accuracy grade and packaging type. Ensure compatibility with system input voltage ranges, noting the minimum requirement of 2.7 V. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Validate that post-assembly X-ray inspection is avoided or minimized to prevent permanent changes in device output voltage.

Selection Notes

Select this component when both ultra-low power consumption and high DC accuracy are critical requirements. The 2.5 V output suits applications interfacing with ADCs/DACs requiring mid-rail references. Consider the SOT-23-3 package for space-constrained PCB layouts. Evaluate the 7 mA drive capability against load requirements; higher current needs may require external buffering or different part selection.

Part Context

The ISL60002BIH326Z belongs to the ISL60002 series of low dropout micropower bandgap voltage references. This family offers various 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. The 'B' indicates ±1.0 mV initial accuracy, while 'H3' denotes the SOT-23-3 package. The '25' specifies the 2.5 V output version.

Replacement Considerations

Direct substitutes include other ISL60002 variants with matching output voltage and accuracy grades, such as ISL60002BIH325Z for 2.5 V with same accuracy. Verify pinout compatibility and thermal performance before substitution. Cross-reference with newer Renesas equivalents if Intersil branding is obsolete.
