Is there a KiCad symbol and footprint for the PAM8403?
Yes. The symbol is EasyEDA_Cloud:PAM8403 and the footprint Package_SO:SOIC-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 PAM8403?
SOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the PAM8403 datasheet?
Slkor publishes it: the Datasheet link on this page opens it.
Where can I order the PAM8403?
JLCPCB lists it as part C5122557, with 4,261 in stock; the sellers' links on this page open their listings.
What can replace the PAM8403?
Parts like it in the library: the PAM8406DR by Diodes Incorporated, the IRS2092STRPBF by Infineon Technologies, the IRS20957STRPBF by Infineon Technologies and the PAM8403DR-H by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the PAM8403?
44 boards in 33 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
