Voltage Reference Procurement Notes

Verify the specific suffix 'BMFX' against the official datasheet to confirm the exact accuracy grade and packaging type. Ensure compatibility with existing PCB footprints and thermal requirements. Confirm availability status as distribution channels may vary.

Voltage Reference Selection Notes

Select this component when a 2.048 V reference with 0.1% initial accuracy is required. Compare temperature coefficients and quiescent current against alternatives if ultra-low power or higher precision is needed. Verify input voltage headroom requirements relative to the 6 V maximum limit.

Voltage Reference Part Context

Part of the LM4132 family of micropower shunt voltage references. Designed for applications needing stable reference voltages in small packages. Offers improved performance over standard references while maintaining low current consumption suitable for battery-operated devices.

Voltage Reference Replacement Considerations

Check for direct substitutes like LM4132AMFX-2.0 or LM4132EMFX-2.0/NOPB based on required accuracy and drift specifications. Ensure pinout compatibility and thermal characteristics match the original design constraints.
