Is there a KiCad symbol and footprint for the LM4890?
Yes. the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM4890?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM4890 datasheet?
IDCHIP publishes it: the Datasheet link on this page opens it.
Where can I order the LM4890?
JLCPCB lists it as part C51018346, with 1,301 in stock; the sellers' links on this page open their listings.
What can replace the LM4890?
Parts like it in the library: the FM8002A by FM, the 8002A by IDCHIP, the NS4150C by Shenzhen Nsiway Tech and the SC8002B by FM. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM4890?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
