X60008BIS8-41

Overview

The X60008BIS8-41 is a precision voltage reference delivering a nominal output of 4.096V, fabricated using Intersil's proprietary Floating Gate Analog (FGA) technology. It provides an absolute initial accuracy of ±0.5mV and a temperature coefficient of 3ppm/°C over the -40°C to +85°C industrial range. The device operates on a single supply voltage between 4.5V and 9.0V with an ultra-low typical supply current of 500nA. It features a 10mA source and sink current capability, 5kV ESD protection, and is housed in an 8-lead SOIC package.

Procurement Notes

Verify the specific suffix 'I' indicates the Industrial temperature grade (-40°C to +85°C) and 'S8' denotes the 8-lead SOIC package. Confirm RoHS compliance status if lead-free processing is required, noting that 'Z' suffix variants are explicitly Pb-free. Ensure ordering documentation matches the exact part number including all grading and packaging suffixes to guarantee correct electrical specifications.

Selection Notes

Select this component when system design demands minimal quiescent current alongside high voltage stability. The FGA technology offers distinct advantages in long-term drift performance compared to standard bandgap references. Consider the 10mA drive capability for direct load interfacing or use external buffering for higher current requirements. Evaluate noise reduction networks if operating in sensitive analog front-end applications.

Part Context

This device belongs to the X60008 series of precision voltage references manufactured by Intersil Americas Inc., now part of Renesas Electronics Corporation. The series leverages specialized floating gate CMOS processes to achieve performance metrics unattainable with traditional reference architectures. It serves as a foundational reference element for high-accuracy data acquisition and measurement instrumentation.

Replacement Considerations

X60008CIS8-41: Offers ±0.5mV accuracy with a 5ppm/°C temperature coefficient. X60008DIS8-41: Provides ±1.0mV accuracy with a 10ppm/°C temperature coefficient. Both maintain identical pinouts, supply ranges, and package styles for direct substitution where relaxed drift specifications are acceptable.

FAQ

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

The FGA technology stores charge precisely on a floating gate cell during manufacturing, resulting in excellent long-term stability of 10 ppm/1000 hours at 25°C, which is superior to conventional bandgap or buried zener technologies.

What is the recommended turn-on time for this device?

Due to the ultra-low supply current, the internal circuitry requires time to bias up. The typical turn-on time is 7ms, but it can last up to approximately 12ms depending on unit variations; system designs should account for this delay before initiating measurements.

Can the X60008BIS8-41 operate continuously in battery-powered circuits?

Yes, its ultra-low supply current of typically 500nA makes it practical for continuous operation in battery-powered circuits without significant power penalty, allowing data converters to remain powered between conversions for highest accuracy.
