Questions

Is there a KiCad symbol and footprint for the REF5040ID?

Yes. The symbol is Reference_Voltage:REF5040ID and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the REF5040ID?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the REF5040ID datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the REF5040ID?

JLCPCB lists it as part C524002, with 16 in stock; the sellers' links on this page open their listings.

What can replace the REF5040ID?

Parts like it in the library: the ADR4540BRZ-R7 by Analog Devices, the ADR444BRZ-REEL7 by Analog Devices, the ADR4540ARZ-R7(TOKMAS) by Tokmas and the GM7401ARZ-4.096-R7 by GONGMOSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the REF5040ID?

5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
