Questions

Is there a KiCad symbol and footprint for the ADS7820PB?

Yes. The symbol is EasyEDA_Cloud:ADS7820P and the footprint Package_DIP:DIP-28_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 ADS7820PB?

DIP-28, with 28 pins. Its footprint is drawn on this page.

Where is the ADS7820PB datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the ADS7820PB?

JLCPCB lists it as part C6459645, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ADS7820PB?

Parts like it in the library: the AD1674KNZ by Analog Devices, the AD574AKNZ by Analog Devices, the AD674BJNZ by Analog Devices and the AD7721AN by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
