Questions

Is there a KiCad symbol and footprint for the ADA4940-1ARZ-R7?

Yes. The symbol is EasyEDA_Cloud:ADA4940-1ARZ-R7 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 ADA4940-1ARZ-R7?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the ADA4940-1ARZ-R7 datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the ADA4940-1ARZ-R7?

JLCPCB lists it as part C730049, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ADA4940-1ARZ-R7?

Parts like it in the library: the THS4521ID by Texas Instruments, the INA132UA/2K5 by Texas Instruments, the LMH6551MAX by Texas Instruments and the THP210D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
