LT1634BIS8-5#TRPBF

Voltage Reference Overview

The LT1634BIS8-5#TRPBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output of 5V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 25ppm/°C. The device operates at a minimum current of 15µA and features low dynamic impedance, ensuring stability with capacitive loads without requiring external compensation. It is housed in an 8-lead plastic SOIC package and supports an industrial operating temperature range from –40°C to +85°C.

Voltage Reference Feature Summary

• Utilizes bandgap reference technology with trimmed precision thin film resistors for high accuracy
• Operates at micropower levels with a minimum current requirement of 15µA
• Stable with capacitive loads and does not require an output compensation capacitor
• Features low dynamic impedance for easy integration with unregulated supplies

Voltage Reference Applications

• Portable meters
• Precision regulators
• A/D and D/A converters
• Calibrators

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with lead-free finish. Confirm the BIS8 designation corresponds to the industrial temperature grade (-40°C to +85°C) and the 8-lead SOIC package. Ensure compatibility with existing PCB footprints for the S8 package type before procurement.

Voltage Reference Selection Notes

Select this component when a 5V shunt reference with ±0.05% initial accuracy is required. It is suitable for applications needing low power consumption (15µA min) and operation across the full industrial temperature range. Consider it as a high-performance upgrade over older references like the LM185 or LT1034 where lower power and guaranteed drift are critical.

Voltage Reference Part Context

The LT1634 series includes various voltage options (1.25V, 2.5V, 4.096V, 5V) and packages (SO-8, MSOP, TO-92). The BIS8 variant specifically denotes the 5V version in the narrow SOIC package with industrial temperature rating. It belongs to the family of micropower precision shunt references designed for portable and battery-powered instrumentation.

Voltage Reference Replacement Considerations

Public confirmed substitutes include LT1634BCS8-5#TRPBF for commercial temperature range applications.
