The LM4041BIM3X-1.2 is a micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 1.225 V with an initial accuracy of ±0.2% at 25°C. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 150 ppm/°C. It utilizes a SOT-23-3 surface-mount package and supports a maximum shunt current of 12 mA.
Verify the manufacturer designation carefully, as the component was originally produced by National Semiconductor before its acquisition by Texas Instruments. Confirm that the specific suffix corresponds to the desired accuracy grade and package variant. Ensure compatibility with existing PCB footprints for the SOT-23-3 package during integration.
Select this component when a low-cost, fixed 1.225 V reference is required for micro-power designs. It is suitable for applications where board space is limited and moderate precision is sufficient. Consider alternative grades if tighter accuracy or lower temperature coefficients are necessary for the specific circuit requirements.
This part belongs to the LM4041-N family of precision micropower shunt voltage references. The family includes adjustable versions and various accuracy grades. The 'B' suffix typically denotes the ±0.2% accuracy grade, while 'M3' indicates the SOT-23-3 package configuration. The 'NOPB' suffix often signifies lead-free and RoHS compliance.
LM4041DIM3X-1.2/NOPB offers similar functionality with ±0.1% accuracy. LM4041DEM3X-1.2/NOPB provides ±1% accuracy. Both are direct pin-compatible alternatives within the same package family.
