X60008BIS8-25T1

Overview

The X60008BIS8-25T1 is a precision 2.5V voltage reference utilizing Intersil's proprietary Floating Gate Analog (FGA) technology, fabricated by Renesas Electronics Corporation. It delivers 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 supply voltage between 4.5V and 6.5V with ultra-low supply current typically at 500nA. It features 10mA source/sink capability, 10ppm/1000hrs long-term stability, and 5kV ESD protection. Packaged in an 8-lead SOIC.

Feature Summary

• Utilizes proprietary Floating Gate Analog technology for superior drift and power performance compared to conventional bandgap or zener references.
• Provides high initial accuracy and low temperature coefficient options for precision applications requiring minimal calibration.
• Features ultra-low power consumption enabling continuous operation in battery-powered systems without significant drain.
• Includes robust protection characteristics such as 5kV ESD tolerance and short-circuit current limiting.

Applications

• High resolution A/D and D/A converters
• Precision current sources and regulators
• Smart sensors and digital meters
• Strain gage bridges and calibration systems
• Battery management systems

Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging configuration when ordering. Confirm that the 'B' grade corresponds to the required ±0.5mV accuracy and 3ppm/°C temperature coefficient specifications. Ensure the manufacturer designation aligns with Renesas Electronics Corporation following the acquisition history. Check RoHS compliance status if lead-free processing is mandatory for the assembly line.

Selection Notes

Select this component when system design demands extremely low quiescent current to preserve battery life in portable devices. Choose the B-grade variant for applications requiring the tightest initial accuracy and lowest temperature drift within the industrial range. Consider the output noise reduction network requirements if operating with larger load capacitances to maintain stability. Evaluate the turn-on time delay of approximately 7ms to 12ms during system initialization sequences.

Part Context

This part belongs to the X60008 series of FGA voltage references, which also includes C-grade (5ppm/°C) and D-grade (10ppm/°C) variants. The series is designed to replace higher-power conventional references in precision analog circuits. The SOIC package offers standard surface-mount compatibility for industrial and commercial PCB layouts.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Intersil/Renesas FGA series parts only if electrical parameters match exactly. Verify pinout compatibility and thermal characteristics before substitution.

FAQ

What is the typical turn-on time for the X60008BIS8-25T1?

The normal turn-on time is typically 7ms, but can last up to about 12ms due to variations in supply current down to 300nA.

How does the X60008 handle output noise with large capacitive loads?

For load capacitances above 0.001µF, a noise reduction network using a 0.01µF capacitor, a 2kΩ resistor, and a 10µF capacitor is recommended to reduce noise and prevent instability.

What is the significance of the DNC pins on the SOIC package?

The DNC (Do Not Connect) pins are internal connections that must be left floating. No connections are permitted to these pins.
