Voltage Reference Procurement Notes

Verify the specific suffix 'DMF' indicates the correct accuracy grade (0.2%) and tape/reel packaging configuration. Confirm that the 'NOPB' designation ensures lead-free and RoHS compliance as per manufacturer specifications. Ensure the ordering part number matches the required output voltage and package type for your design implementation.

Voltage Reference Selection Notes

Select this component when a 2.5 V reference with 0.2% initial accuracy is required in a small SOT-23-5 footprint. It is suitable for designs prioritizing low power consumption alongside moderate precision. Consider alternative grades if tighter accuracy or lower noise specifications are necessary for the application.
