X60008DIS8-50

Overview

The X60008DIS8-50 is a precision voltage reference utilizing Intersil's proprietary Floating Gate Analog (FGA) technology. It provides a stable 5.000V output with an absolute initial accuracy of ±1.0mV and a temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 5.1V to 9.0V, drawing a typical supply current of 500nA. It features a low dropout voltage of 100mV at no load and supports 10mA source and sink currents. Packaged in an 8-lead SOIC format, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior long-term stability and ultra-low power consumption compared to conventional band gap or Zener references.
• Delivers high precision performance characterized by very low temperature drift and excellent line and load regulation capabilities.
• Designed for battery-operated systems due to nanowatt-level supply current, allowing continuous biasing without significant power penalty.

Applications

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

Procurement Notes

Verify the specific grade suffix 'D' corresponds to the required ±1.0mV accuracy and 10ppm/°C temperature coefficient specifications. Confirm that the 'S8' package designation matches the 8-lead SOIC footprint requirements for your PCB layout. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when system design demands minimal quiescent current alongside high DC accuracy. The FGA technology offers distinct advantages over standard bandgap references regarding long-term drift and noise performance. Consider the 100mV dropout voltage when determining the minimum input supply voltage relative to the load conditions and desired regulation margins.

Part Context

The series leverages floating gate CMOS processes to achieve performance levels unattainable with traditional analog reference technologies. The X60008DIS8-50 represents the industrial grade variant optimized for general-purpose high-precision applications requiring robust stability.

Replacement Considerations

X60008CIS8-50: Offers tighter accuracy (±0.5mV) and lower tempco (5ppm/°C).

FAQ

How does the Floating Gate Analog technology impact long-term stability?

The stored charge on the floating gate cell is set precisely during manufacturing, resulting in excellent long-term stability of 10 ppm per 1000 hours at 25°C.

What is the recommended output capacitance for noise reduction?

A 0.001µF capacitor is typically used on the output. For further noise reduction above 0.001µF, a network including a 2kΩ resistor and 10µF capacitor is recommended to prevent instability.
