Is there a KiCad symbol and footprint for the LM4864M?
Yes. The symbol is EasyEDA_Cloud:LM4864N 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 LM4864M?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM4864M datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM4864M?
JLCPCB lists it as part C2869749, with 10 in stock; the sellers' links on this page open their listings.
What can replace the LM4864M?
Parts like it in the library: the TC8002D by FM, the LM833D by onsemi, the LM4871MX by Texas Instruments and the FM8002E by Shenzhen Fuman Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM4864M?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
