LT1634ACS8-5#TRPBF

Voltage Reference Overview

The LT1634ACS8-5#TRPBF is a micropower precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5V with an initial accuracy of ±0.05%. The device operates at a low current of 10µA and features a maximum temperature drift of 10ppm/°C. It exhibits less than 1Ω dynamic impedance and does not require an output compensation capacitor, remaining stable with capacitive loads. The component is housed in an 8-lead plastic SOIC package and supports commercial operating temperatures from 0°C to 70°C.

Voltage Reference Feature Summary

• Utilizes trimmed precision thin film resistors for high initial voltage accuracy
• Operates at extremely low quiescent current suitable for battery-powered applications
• Features improved curvature correction for minimal temperature drift
• Capable of driving capacitive loads without external compensation

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to tape and reel packaging rather than tube packaging when sourcing components. Confirm that the ACS8 designation aligns with the required 8-lead SOIC package dimensions and thermal characteristics. Ensure the manufacturer part number matches the exact voltage grade and temperature range specifications required for the design.

Voltage Reference Selection Notes

Select this component when a precise 5V reference is needed with minimal power consumption. The low dynamic impedance allows operation directly from unregulated supplies. Consider the ±0.05% initial accuracy and 10ppm/°C drift for high-performance analog signal chains. Verify compatibility with existing PCB footprints for the 8-lead SOIC package during the integration phase.

Voltage Reference Part Context

This device belongs to the LT1634 family of micropower precision shunt voltage references. It serves as a high-performance upgrade to legacy parts like the LM185, LM385, LT1004, and LT1034, offering lower power consumption and guaranteed temperature drift. The family includes various voltage options and package types to suit different design constraints.
