LM4041DIX3-1.2+T

Voltage Reference Overview

The LM4041DIX3-1.2+T is a precision two-terminal shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 1.0% at +25°C and a maximum temperature coefficient of 150ppm/°C. The device operates within a wide current range from 60µA to 12mA, ensuring stable performance across varying loads. It features low dynamic impedance and output noise of 20µVRMS (10Hz to 10kHz). Packaged in the subminiature SC70-3 surface-mount format, it is guaranteed for operation over the industrial temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC70 package designed for space-critical applications
• Laser-trimmed resistors ensure precise initial accuracy without external components
• Capable of tolerating capacitive loads without requiring external stabilizing capacitors
• Low dynamic impedance maintains stable reverse-breakdown voltage accuracy

Voltage Reference Applications

• Portable, battery-powered equipment
• Notebook computers
• Cell phones
• Industrial process controls

Voltage Reference Procurement Notes

Verify that the ordering suffix 'IX3' corresponds specifically to the SC70-3 package type as defined in the manufacturer's selector guide. Confirm that the '+T' designation indicates lead-free/RoHS-compliant packaging. Ensure the 'D' grade selection aligns with the required 1.0% initial accuracy specification for the target design.

Voltage Reference Selection Notes

Select this component when a compact footprint is prioritized alongside moderate precision requirements. The 1.0% accuracy grade offers a balance between cost and performance compared to tighter tolerance options. Verify that the operating environment remains within the specified -40°C to +85°C range to maintain guaranteed electrical characteristics.

Voltage Reference Part Context

This part belongs to the LM4041 series of micropower shunt voltage references. The series includes variants with different accuracy grades (0.1%, 0.2%, 0.5%, 1.0%) and temperature ranges (-40°C to +85°C or -40°C to +125°C). The specific model utilizes the SC70-3 package, which is approximately 50% smaller than the comparable SOT23-3 option available in the same family.
