X60008CIS8-41T1

Overview

The X60008CIS8-41T1 is a precision voltage reference delivering a fixed 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 industrial range of -40°C to +85°C. The device operates with an ultra-low supply current of typically 500nA and supports a supply voltage range from 4.5V to 9.0V. It features a 10mA source and sink current capability, 10ppm/1000hrs long-term stability, and low dropout voltage. Packaged in an 8-lead SOIC, it includes 5kV ESD protection.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior drift and power performance compared to conventional bandgap or Zener references.
• Delivers high initial accuracy and low temperature coefficient to ensure stable reference voltages across varying environmental conditions.
• Features extremely low supply current consumption, enabling continuous operation in battery-powered systems without significant drain.
• Provides robust noise reduction capabilities and high line/load regulation suitable for demanding analog signal chains.

Applications

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

Procurement Notes

Verify that the ordering suffix 'T1' corresponds to tape and reel packaging as specified in the datasheet. Confirm the 'C' grade designation matches the required 5ppm/°C temperature coefficient and ±0.5mV initial accuracy. Ensure the manufacturer documentation aligns with the specific part number X60008CIS8-41T1 before procurement.

Selection Notes

Select this component when designing systems requiring high precision with minimal power consumption. The 5ppm/°C temperature coefficient makes it suitable for applications where thermal stability is critical. Consider the 7ms typical turn-on time during system initialization planning. The 10mA drive capability allows direct interfacing with certain loads, though external buffering may be needed for higher currents.

Part Context

This component belongs to the X60008 series of FGA™ voltage references, which also includes the X60008B-41 (3ppm/°C) and X60008D-41 (10ppm/°C) variants. All share the same 4.096V output and package options but differ in accuracy grades. The series is designed to replace conventional references in portable and industrial applications requiring lower power and higher stability.

Replacement Considerations

Direct substitutes include the X60008BIS8-41T1 for tighter 3ppm/°C accuracy or the X60008DIS8-41T1 for relaxed 10ppm/°C tolerance. Verify pin compatibility and electrical specifications against the original design requirements when selecting alternative grades within the same family.

FAQ

What is the typical turn-on time for the X60008C-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 X60008 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 or a specific RC network recommended in the datasheet.

What is the maximum short circuit current?

The short circuit current is guaranteed to be between 50mA and 80mA at 25°C.
