LM4041CIM7-ADJ

Overview

The LM4041CIM7-ADJ is a micropower shunt voltage reference manufactured by Texas Instruments, which acquired National Semiconductor. It provides an adjustable output voltage within the series range. The device features an initial accuracy of 0.5% and a temperature coefficient of 150 ppm/°C. It operates with a maximum shunt current of 12 mA across a temperature range of -40°C to +125°C. The component is housed in an SC-70-5 surface-mount package.

Feature Summary

• Micropower operation suitable for power-restricted designs
• Adjustable output voltage capability
• High precision with low temperature drift
• Stable performance under capacitive loads

Applications

• Portable battery-powered equipment
• Data acquisition systems
• Instrumentation
• Process control
• Precision audio components

Procurement Notes

Verify that the manufacturer designation aligns with Texas Instruments, as National Semiconductor was acquired. Confirm the specific suffix indicates the adjustable variant and the SC-70-5 package type. Ensure the order matches the required 0.5% initial accuracy and extended temperature rating specifications documented for this part number.

Selection Notes

Select this component when space-saving surface-mount packaging is required alongside adjustable reference functionality. The low operating current makes it suitable for battery-operated applications. Verify that the 150 ppm/°C temperature coefficient meets the system's thermal stability requirements compared to lower-drift alternatives.

Part Context

This component belongs to the LM4041 series of precision micropower shunt voltage references. The series includes fixed and adjustable versions available in various packages such as SOT-23-3L and SOT323-5L. The LM4041 family is designed for applications requiring high accuracy and low power consumption in compact form factors.

Replacement Considerations

LM4041DIM7-ADJ/NOPB offers similar specifications but with 1% initial accuracy.
