LT1634AIS8-2.5#TRPBF

Voltage Reference Overview

The LT1634AIS8-2.5#TRPBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed 2.5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within the industrial temperature range of –40°C to +85°C and is housed in an 8-lead plastic SO package. It features low operating current, dynamic impedance below 1Ω, and stability with capacitive loads without requiring external compensation.

Voltage Reference Feature Summary

• Micropower precision shunt voltage reference utilizing bandgap technology with trimmed thin film resistors for high accuracy.
• Low operating current consumption and less than 1Ω dynamic impedance for easy integration from unregulated supplies.
• Guaranteed low drift performance with improved curvature correction techniques ensuring minimal temperature cycling hysteresis.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix #TRPBF indicates tape and reel packaging. Ensure the ordering code matches the required industrial temperature grade and package type. Request original datasheets and material declarations to validate compliance specifications prior to procurement.

Voltage Reference Selection Notes

Select this part when upgrading from LM185/LM385, LT1004, or LT1034 references where lower power consumption and guaranteed temperature drift are critical requirements. Choose the AIS8 variant specifically for designs necessitating operation across the full industrial temperature range of –40°C to +85°C.

Voltage Reference Part Context

This component belongs to the LT1634 family of micropower precision shunt voltage references. The 'A' designation denotes commercial/industrial grade performance with tighter drift specifications compared to the 'B' series. The 'IS8' suffix identifies the specific industrial temperature range and 8-lead SOIC package configuration.
