Voltage Reference Procurement Notes

Verify the specific suffix 'EEM3' against official Texas Instruments documentation to confirm the exact grade and tape-and-reel specifications. Ensure compatibility with standard SOT-23 footprints during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental files before final procurement.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is required in a minimal footprint. The absence of external stabilization requirements simplifies circuit design. Consider the ±0.5% initial accuracy and 150 ppm/°C drift characteristics against system tolerance requirements. Verify that the 60 µA minimum operating current aligns with the application's quiescent current constraints.

Voltage Reference Part Context

This part belongs to the LM4041-N family of precision micropower shunt voltage references from Texas Instruments. The family offers both fixed and adjustable versions in sub-miniature packages like SC-70 and SOT-23. These devices are engineered for high accuracy using fuse and Zener-zap reverse breakdown trim during wafer sort.

Voltage Reference Replacement Considerations
