X60008CIS8-25

Overview

The X60008CIS8-25 is a precision voltage reference utilizing Intersil’s proprietary Floating Gate Analog (FGA) technology. It provides a nominal output of 2.5V with an absolute initial accuracy of ±0.5mV and a temperature coefficient of 5ppm/°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/sink capability, 10ppm/1000hrs long-term stability, and 5kV ESD protection. Packaged in an 8-lead SOIC, it supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior performance compared to conventional band gap or buried zener references.
• Delivers high initial accuracy and low temperature drift while maintaining ultra-low power consumption suitable for battery-operated systems.
• Provides robust noise reduction capabilities through specific output capacitance configurations and external filtering networks.

Applications

• High resolution A/Ds & D/As
• Precision Current Sources
• Smart sensors
• Digital Meters
• Calibration Systems

Procurement Notes

Verify the specific suffix 'I' indicates the ±0.5mV accuracy grade and 'S8' denotes the 8-lead SOIC package. Confirm RoHS compliance status if lead-free processing is required, as indicated by the 'Z' suffix variant. Ensure input voltage remains within the 4.5V to 6.5V range to maintain specified line regulation and stability characteristics during operation.

Selection Notes

Select this component when ultra-low quiescent current is critical for extending battery life in portable instrumentation. The 5ppm/°C temperature coefficient offers a balance between the higher precision B-grade and the standard D-grade options. Consider the 10mA drive capability for direct loading of low-impedance circuits without additional buffering stages.

Part Context

This part belongs to the X60008 series of FGA™ voltage references manufactured by Intersil Americas Inc. The series includes variants with different accuracy grades (B, C, D) and temperature coefficients. The X60008C specifically targets applications requiring moderate precision with lower power consumption than traditional bandgap references.

Replacement Considerations

X60008BIS8-25: Offers tighter accuracy (±0.5mV) and lower tempco (3ppm/°C). X60008DIS8-25: Features looser accuracy (±1.0mV) and higher tempco (10ppm/°C). Both share identical pinouts and electrical operating conditions.

FAQ

How does the X60008 achieve such low power consumption?

It uses proprietary Floating Gate Analog technology where charge stored on a floating gate cell is set precisely during manufacturing, eliminating the need for continuous high-current biasing found in conventional references.

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 in series is recommended to significantly reduce noise across the full bandwidth.
