LM4040DIX3-2.5

Overview

The LM4040DIX3-2.5 is a micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated, featuring a fixed output of 2.5 V with an initial accuracy of 1%. It operates within a temperature range of -40°C to +85°C and exhibits a maximum temperature coefficient of 30 ppm/°C. The device supports a maximum shunt current of 15 mA and utilizes a SC-70-3 surface-mount package.

Feature Summary

• Provides stable precision voltage reference performance in compact surface-mount packaging
• Designed for applications requiring low operating current and high accuracy over industrial temperatures

Applications

• Portable instrumentation circuits
• Battery-powered measurement systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'DIX3' against official manufacturer documentation to confirm the exact tolerance grade and reel specifications. Confirm availability status as distribution channels may list limited stock or obsolete variants. Ensure the SC-70-3 footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when a 1% accuracy level at 2.5 V is sufficient for the application. Consider the 30 ppm/°C temperature coefficient for thermal stability needs. Verify that the SC-70-3 package dimensions fit the spatial constraints of the design compared to larger packages like SOT-23.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various accuracy grades (A, B, C, D) and output voltages. The 'D' designation indicates the 1% initial accuracy tier, while 'IX3' specifies the SC-70-3 surface-mount package configuration.
