Is there a KiCad symbol and footprint for the LM1815M?
Yes. The symbol is EasyEDA_Cloud:LM1815M_NOPB and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM1815M?
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Where is the LM1815M datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM1815M?
JLCPCB lists it as part C17562406, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM1815M?
Parts like it in the library: the LS6511N-S by LSI/CSI, the LS6512-S by LSI/CSI, the LS6525-S by LSI/CSI and the LS6526-S by LSI/CSI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM1815M?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
