LT1634ACS8-1.25#PBF

Voltage Reference Overview

The LT1634ACS8-1.25#PBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SO (SOIC) package. It provides a fixed output voltage 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 10ppm/°C. Key electrical characteristics include a minimum operating current of 7µA, low-frequency noise of 10µVP-P (0.1Hz to 10Hz), and reverse dynamic impedance below 1Ω.

Voltage Reference Feature Summary

Utilizes trimmed precision thin film resistors for high initial voltage accuracy
Features improved curvature correction technique to ensure low temperature drift
Capable of operation from unregulated supplies due to low dynamic impedance
Stable with capacitive loads without requiring external output compensation

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 when sourcing. Confirm the 'A' grade designation matches the required 10ppm/°C temperature coefficient specification. Ensure the 8-lead SOIC footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when upgrading legacy references like LM185 or LT1004 where lower power consumption and guaranteed temperature drift are critical requirements. The 1.25V output is suitable for applications needing a stable baseline reference. Verify that the 0°C to 70°C commercial temperature range meets the environmental conditions of the intended system design.

Voltage Reference Part Context

This part belongs to the LT1634 family of micropower precision shunt voltage references. The family offers various output voltages including 2.5V, 4.096V, and 5V, available in both MSOP and SO packages. The LT1634 series is designed to replace older generation references while providing superior performance in terms of power efficiency and thermal stability.
