Is there a KiCad symbol and footprint for the CA3140?
Yes. The symbol is Amplifier_Operational:CA3140 and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CA3140?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the CA3140 datasheet?
Gcore publishes it: the Datasheet link on this page opens it.
Where can I order the CA3140?
JLCPCB lists it as part C5157700, with 259 in stock; the sellers' links on this page open their listings.
What can replace the CA3140?
Parts like it in the library: the LMV722AIN by HGSEMI, the LMV721AIN by HGSEMI, the ICL7611ACPA-TUDI by Tudi and the ICL7611BCPA-TUDI by Tudi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CA3140?
21 boards in 16 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
