Questions

Is there a KiCad symbol and footprint for the LM4890S?

Yes. The symbol is EasyEDA_Cloud:LM4890S_C329452 and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4890S?

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

Where is the LM4890S datasheet?

IDCHIP publishes it: the Datasheet link on this page opens it.

Where can I order the LM4890S?

JLCPCB lists it as part C329452, with 14,026 in stock; the sellers' links on this page open their listings.

What can replace the LM4890S?

Parts like it in the library: the NS4150B by Shenzhen Nsiway Tech, the LM4890SS by IDCHIP, the LN4890MME-G by NATLINEAR and the PAM8302AASCR by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM4890S?

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