ISL60002BIH325

Overview

The ISL60002BIH325 is a precision series voltage reference IC from Renesas, utilizing proprietary Floating Gate Analog (FGA) technology. It provides a fixed 2.5V output with an initial accuracy of ±0.2% and a temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V, drawing an ultra-low supply current of 900nA. It supports a maximum output current of 7mA for both sourcing and sinking. Packaged in a compact SOT-23-3 surface-mount format, it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Employs proprietary Floating Gate Analog (FGA) technology for high precision and stability
• Delivers guaranteed initial accuracy of ±0.2% at 2.5V output
• Features ultra-low power consumption with 900nA supply current
• Includes robust ESD protection rated at 5.5kV (Human Body Model)

Applications

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

Procurement Notes

Verify the specific suffix 'Z' for RoHS compliance when ordering, as standard listings may vary. Confirm package type is SOT-23-3. Check for post-assembly X-ray inspection warnings in the datasheet, as this may permanently alter output voltage. Ensure compatibility with industrial temperature ranges if operating outside standard limits.

Selection Notes

Select this component for applications requiring low noise and high thermal stability without compromising power efficiency. The FGA technology ensures long-term drift performance superior to traditional bandgap references. Consider the 7mA drive capability for direct interfacing with ADC inputs or sensor bridges. Verify input voltage stays within the 2.7V to 5.5V window for optimal regulation.

Part Context

This part belongs to the ISL60002 family of micropower voltage references. The family offers various output voltages including 1.024V, 1.25V, and 3.3V. The 'B' suffix typically denotes ±0.2% accuracy, while 'H325' specifies the 2.5V output and SOT-23-3 package. These devices are designed for battery-powered and portable instrumentation where power conservation is critical.

Replacement Considerations

Direct substitutes include other ISL60002 variants with matching accuracy and voltage, such as ISL60002DIH325 for ±0.5% tolerance or ISL60002CIH325 for ±0.1% tolerance. Cross-reference with Renesas' current portfolio as older Intersil-branded parts may have different packaging or RoHS statuses.
