Is there a KiCad symbol and footprint for the OPA685U?
Yes. The symbol is EasyEDA_Cloud:OPA685U 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 OPA685U?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA685U datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA685U?
JLCPCB lists it as part C4366681, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA685U?
Parts like it in the library: the BUF634AID by Texas Instruments, the OPA551UA/2K5 by Texas Instruments, the RS8452XK-Q1 by Jiangsu RUNIC Tech and the RS8702XK by Jiangsu RUNIC Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
