Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet FN8137 to confirm exact electrical tolerances and packaging variants. Ensure compatibility with existing board layouts due to the SOT-23-3 footprint. Cross-reference part numbers carefully as Intersil products are now managed under Renesas Electronics; confirm supply chain authenticity through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 4.096V reference with tight initial accuracy is required in a minimal footprint. The low power consumption makes it ideal for battery-operated equipment where quiescent current must be minimized. Consider the thermal performance and ambient operating conditions to ensure the temperature coefficient remains within acceptable limits for the specific application environment.

Part Context

This component belongs to the X60003 family of voltage references developed by Intersil Corporation, which was subsequently acquired by Renesas Electronics. The series is characterized by its use of FGA technology to achieve high precision without external trimming. These parts are widely used in industrial and consumer electronics requiring reliable, stable voltage references for sensitive analog circuits.

Replacement Considerations

Direct substitutes include other 4.096V SOT-23 voltage references such as the LM4040AIM3-4.1 or REF3340, provided pinouts and electrical specifications match. Verify that alternative components meet the same temperature coefficient and accuracy requirements. Check for any differences in startup time or noise performance that might impact system stability.
