X60008CIS8-41

Overview

The X60008CIS8-41 is a precision voltage reference delivering a nominal output of 4.096V, manufactured using Intersil's proprietary Floating Gate Analog (FGA) technology. It provides an absolute initial accuracy of ±0.5mV and a temperature coefficient of 5ppm/°C over the -40°C to +85°C industrial range. The device operates on a supply voltage between 4.5V and 9.0V with ultra-low power consumption of typically 500nA. It features 10mA source/sink current capability, 100mV dropout voltage, and 5kV ESD protection in an 8-lead SOIC package.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior long-term stability and low drift compared to conventional bandgap references.
• Delivers high precision with ±0.5mV initial accuracy and 5ppm/°C temperature coefficient across the industrial temperature range.
• Features ultra-low supply current of 500nA, enabling continuous operation in battery-powered systems without significant drain.
• Provides robust performance with 5kV ESD protection and 10mA source/sink current capability.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'Z' if lead-free compliance is required, as standard parts may differ. Confirm the package type matches the design requirements, as this model uses an 8-lead SOIC. Ensure the input voltage remains within the 4.5V to 9.0V range for guaranteed specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select the X60008CIS8-41 when a balance of moderate temperature coefficient (5ppm/°C) and tight initial accuracy (±0.5mV) is needed. It is suitable for applications requiring lower power than traditional references but higher precision than standard shunt regulators. Consider the 7ms turn-on time for system timing constraints. Evaluate noise reduction needs, as external filtering may be required for very low noise applications.

Part Context

This component belongs to the X60008 series of FGA™ voltage references, originally developed by Intersil Americas Inc. The series includes variants with different accuracy grades (B, C, D) and temperature coefficients. The X60008C-41 specifically targets industrial applications requiring stable, low-power precision references. The technology leverages stored charge on floating gates rather than bandgap voltages.

Replacement Considerations

Direct substitutes include X60008BIS8-41 for tighter temperature coefficient (3ppm/°C) or X60008DIS8-41 for relaxed accuracy (±1.0mV). Verify pin compatibility and thermal characteristics when swapping. Note that Intersil products are now part of Renesas Electronics; check for updated datasheets or equivalent modern replacements from Renesas if sourcing new production units.

FAQ

What is the typical turn-on time for the X60008CIS8-41?

The typical turn-on time is approximately 7ms, though it can extend up to 12ms depending on the specific unit's supply current variations.

How does the X60008CIS8-41 handle output noise?

The output noise is typically 30µVp-p in the 0.1Hz to 10Hz bandwidth. Higher frequency noise can be reduced using external capacitors, such as a 0.001µF capacitor at the output.

Can the X60008CIS8-41 operate continuously in battery-powered circuits?

Yes, its ultra-low supply current of 500nA makes it practical for continuous operation in battery-powered circuits without significantly draining the battery.
