LM4041DIX3-1.2

Voltage Reference Overview

The LM4041DIX3-1.2 is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated, providing a fixed output of 1.225 V. It features an initial accuracy of ±1% at 25°C and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23 (SC-70) surface-mount package with three terminals. Key electrical parameters include a maximum temperature coefficient of 150 ppm/°C, a minimum operating current of 73 µA, and a maximum cathode current of 12 mA.

Voltage Reference Feature Summary

• Provides stable 1.225 V reference voltage in sub-miniature packages
• Ensures stability with any capacitive load without external components
• Offers high precision with low temperature drift characteristics

Voltage Reference Applications

• Space-critical portable electronics designs
• Battery-powered measurement instruments
• Data acquisition systems requiring precise references

Voltage Reference Procurement Notes

Verify the manufacturer designation carefully, as the LM4041 series is produced by multiple vendors including Texas Instruments, STMicroelectronics, and Maxim Integrated. Confirm that the specific suffix matches the required accuracy grade and package type for your design. Ensure compatibility with existing supply chains given the multi-source nature of this component family.

Voltage Reference Selection Notes

Select this part when a fixed 1.225 V reference is needed in a small footprint. The ±1% tolerance suits general-purpose applications where tighter grades are unnecessary. Consider the 73 µA minimum current requirement to ensure proper regulation during operation. Evaluate thermal performance if operating near the upper temperature limit.

Voltage Reference Part Context

This component belongs to the LM4041-N family of precision micropower shunt voltage references. The series is designed for applications requiring space-saving solutions and low power consumption. Variants exist with different accuracies and adjustable voltage options, but this specific model provides a fixed 1.225 V output in a SC-70 package.
