LM4040AIX3-5.0-T

Overview

The LM4040AIX3-5.0-T is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated, housed in an SC-70-3 surface-mount package. It provides a fixed output voltage of 5 V with an initial accuracy of 0.1% and a temperature coefficient of 30 PPM/°C. The device supports a maximum shunt current of 15 mA and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high precision voltage referencing with 0.1% initial accuracy
• Features low temperature drift for stable performance across wide thermal ranges
• Designed for space-constrained applications using compact SC-70-3 packaging

Applications

• Portable instrumentation requiring precise voltage standards
• Battery-powered systems needing low quiescent current references
• Data acquisition systems utilizing analog-to-digital conversion

Procurement Notes

Verify the specific suffix 'A' indicates the 0.1% accuracy grade and 'IX3' denotes the SC-70-3 package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement specifications.

Selection Notes

Select this component when strict accuracy requirements of 0.1% are necessary alongside minimal physical footprint. Ensure the operating environment stays within the specified -40°C to +125°C range to maintain the guaranteed 30 PPM/°C temperature coefficient performance.

Part Context

This part belongs to the LM4040 family of improved precision micropower shunt voltage references. It shares architectural similarities with other variants like the LM4040DIX3-5.0-T but offers superior initial accuracy and extended industrial temperature capabilities compared to standard commercial grade options.
