Voltage Reference Overview

The LT1634BCS8-1.25#PBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 1.25V with an initial accuracy of ±0.05%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 25ppm/°C. It utilizes trimmed precision thin film resistors for high stability and low drift, ensuring reliable performance in portable meters, precision regulators, A/D and D/A converters, and calibrators.

Voltage Reference Feature Summary

Achieves 0.05% initial voltage accuracy using trimmed precision thin film resistors
Operates at micropower levels with a minimum operating current of 7µA
Provides stable regulation without requiring an external output compensation capacitor

Voltage Reference Applications

Portable Meters
Precision Regulators
A/D and D/A Converters
Calibrators

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the BC grade corresponds to the 0°C to 70°C commercial temperature range and 25ppm/°C drift specification. Ensure the MSOP-8 package matches the design footprint requirements before procurement.

Voltage Reference Selection Notes

Select this component when a precise 1.25V reference is required in space-constrained designs utilizing the MSOP-8 package. It serves as a direct upgrade for applications needing lower power consumption and guaranteed temperature drift compared to older LM185 or LT1004 references.

Voltage Reference Part Context

This part belongs to the LT1634 family of micropower precision shunt voltage references. It is available in various output voltages (1.25V, 2.5V, 4.096V, 5V) and packages including SO-8, MSOP, and TO-92. The BC grade specifically denotes the commercial temperature variant with standard drift characteristics.
