LM4040BIM7-2.0/NOPB

Overview

The LM4040BIM7-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.048 V. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +125°C. The device utilizes a SC-70-5 surface-mount package with a maximum shunt current of 12 mA and a temperature coefficient of 150 ppm/°C.

Feature Summary

• Provides stable 2.048 V reference in compact SC-70-5 package
• Maintains ±0.2% initial accuracy across extended temperature range
• Supports operation up to 125°C for demanding environments

Applications

• Precision analog-to-digital converter references
• Battery-powered instrumentation circuits
• Temperature-compensated sensor interfaces

Procurement Notes

Verify the specific suffix 'M7' indicates the SC-70-5 package variant distinct from standard SOT-23 versions. Confirm RoHS compliance status via official datasheets. Ensure ordering codes match the exact temperature grade and accuracy class required for your design specifications.

Selection Notes

Select this component when space constraints require the SC-70-5 footprint over larger packages. Choose this part if the application demands operation at temperatures up to 125°C while maintaining high precision. Consider the 12 mA maximum shunt current limit when designing biasing networks.

Part Context

This device belongs to the LM4040 series of micropower shunt references. It shares functional similarities with other LM4040 variants but differs in package type and thermal performance. The series offers various fixed voltage options and accuracy grades for general-purpose reference applications.

Replacement Considerations

LM4040BIM3-2.0/NOPB serves as a pin-compatible alternative using the SOT-23 package, though it typically supports a lower maximum operating temperature of 85°C compared to the M7 variant.
