Is there a KiCad symbol and footprint for the OPA2277U?
Yes. The symbol is Amplifier_Operational:OPA2277 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 OPA2277U?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA2277U datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA2277U?
JLCPCB lists it as part C24668, with 375 in stock; the sellers' links on this page open their listings.
What can replace the OPA2277U?
Parts like it in the library: the GS8552-SR by Gainsil, the OPA2192ID by Texas Instruments, the MAX44248ASA+T by Maxim Integrated (Analog Devices) and the OPA197ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OPA2277U?
9 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
