Questions

Is there a KiCad symbol and footprint for the LM4890MX?

Yes. The symbol is EasyEDA_Cloud:LM4890SS 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 LM4890MX?

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

Where is the LM4890MX datasheet?

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

Where can I order the LM4890MX?

JLCPCB lists it as part C117476, with 4,770 in stock; the sellers' links on this page open their listings.

What can replace the LM4890MX?

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 LM4890MX?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
