Questions
Is there a KiCad symbol and footprint for the LM4990MM?
Yes. The symbol is Amplifier_Audio:LM4990MM and the footprint Package_SO:VSSOP-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 LM4990MM?
VSSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM4990MM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM4990MM?
JLCPCB lists it as part C8958, with 34 in stock; the sellers' links on this page open their listings.
What can replace the LM4990MM?
Parts like it in the library: the OPA1637DGK by Texas Instruments, the OPA1662AIDGKRQ1 by Texas Instruments, the OPA1678IDGK by Texas Instruments and the LM833MM by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM4990MM?
