Is there a KiCad symbol and footprint for the AC7911BA?
Yes. The symbol is EasyEDA_Cloud:AC7911BA and the footprint EasyEDA_Cloud:QFN-48_L6.0-W6.0-P0.40-TL-EP4.1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AC7911BA?
QFN-48-EP(6x6), with 49 pins. Its footprint is drawn on this page.
Where is the AC7911BA datasheet?
JieLi Tech publishes it: the Datasheet link on this page opens it.
Where can I order the AC7911BA?
JLCPCB lists it as part C42389637, with 245 in stock; the sellers' links on this page open their listings.
What can replace the AC7911BA?
Parts like it in the library: the STC8H4K64TLCD-40I-QFN48 by STC Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
