Is there a KiCad symbol and footprint for the LM4870M?
Yes. The symbol is EasyEDA_Cloud:LM4860M_C4990953 and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM4870M?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the LM4870M datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM4870M?
JLCPCB lists it as part C4990738, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM4870M?
Parts like it in the library: the PAM8003DR by Diodes Incorporated, the LM4863DRG by HANSCHIP semiconductor, the SSM2019BRWRL by Analog Devices and the SSM2118TS by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
