Is there a KiCad symbol and footprint for the REF5045ID?
Yes. The symbol is Reference_Voltage:REF5045ID 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 REF5045ID?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the REF5045ID datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the REF5045ID?
JLCPCB lists it as part C2157551, with 23 in stock; the sellers' links on this page open their listings.
What can replace the REF5045ID?
Parts like it in the library: the REF194GSZ by Analog Devices, the REF194ES-REEL by Analog Devices, the REF194ESZ-REEL by Analog Devices and the REF194FS-REEL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the REF5045ID?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
