Is there a KiCad symbol and footprint for the OPA2145ID?
Yes. The symbol is EasyEDA_Cloud:RC4558IDGKR-TUDI and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA2145ID?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA2145ID datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA2145ID?
JLCPCB lists it as part C2862860, with 12 in stock; the sellers' links on this page open their listings.
What can replace the OPA2145ID?
Parts like it in the library: the TL072CDT by STMicroelectronics, the TL082CDT by STMicroelectronics, the TL082IDT by STMicroelectronics and the TL072ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OPA2145ID?
3 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
