X60008BIS8-25

Overview

The X60008BIS8-25 is a precision voltage reference utilizing Intersil's proprietary Floating Gate Analog (FGA) technology. It provides a nominal output voltage of 2.5V with an absolute initial accuracy of ±0.5mV and a temperature coefficient of 3ppm/°C. The device operates within a supply voltage range of 4.5V to 6.5V, drawing a typical supply current of 500nA. It features 10mA source and sink current capability, 10ppm/1000hrs long-term stability, and 5kV ESD protection. The component is housed in an 8-lead SOIC package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior performance compared to conventional band gap or Zener references.
• Delivers ultra-low power consumption suitable for continuous operation in battery-powered systems without significant load impact.
• Provides high initial accuracy and low temperature drift characteristics essential for maintaining precision over time and temperature variations.

Applications

• High resolution analog-to-digital and digital-to-analog converters
• Precision regulators and current sources
• Calibration systems and digital meters
• Strain gage bridges and threshold detectors

Procurement Notes

Verify the specific suffix 'I' indicates the ±0.5mV accuracy grade and 'S8' denotes the 8-lead SOIC package configuration. Confirm that the '-25' suffix corresponds to the 2.5V output variant. Ensure compatibility with RoHS compliance requirements if lead-free versions are required for assembly processes. Check for any tape and reel availability options if indicated by additional ordering suffixes.

Selection Notes

Select this component when system design demands minimal quiescent current alongside high precision. The FGA technology offers advantages in long-term stability and low noise for sensitive measurement applications. Consider the 10mA drive capability for direct loading scenarios. Evaluate the thermal hysteresis specifications against environmental cycling requirements to ensure signal integrity remains within acceptable bounds.

Part Context

This part belongs to the X60008 series of precision voltage references manufactured by Intersil Americas Inc., now part of Renesas Electronics Corporation. The series leverages floating gate CMOS processes to achieve performance metrics distinct from traditional reference architectures. The X60008B variant specifically targets applications requiring the tightest initial accuracy tolerances within the product line.

Replacement Considerations

The datasheet lists X60008BIS8Z-25 as a Pb-free plus anneal alternative within the same accuracy and package specification. Verify pinout compatibility and electrical parameter equivalence before substituting with other manufacturers' devices, as FGA technology characteristics may differ significantly from standard bandgap references.

FAQ

How does the Floating Gate Analog technology affect the power consumption?

The FGA technology enables ultra-low supply current, typically 500nA, which is significantly lower than competitive devices. This allows the reference to remain powered continuously in battery-operated circuits without draining the battery.

What is the recommended method for reducing output noise?

For load capacitances above 0.001µF, a noise reduction network consisting of a 0.01µF capacitor, a 10µF capacitor, and a 2kΩ resistor is recommended to reduce noise across the full bandwidth effectively.
