Is there a KiCad symbol and footprint for the AD7851AR?
Yes. The symbol is EasyEDA_Cloud:AD7851KR and the footprint Package_SO:SOP-24_7.5x15.4mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD7851AR?
SOIC-24, with 24 pins. Its footprint is drawn on this page.
Where is the AD7851AR datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD7851AR?
JLCPCB lists it as part C7459670, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD7851AR?
Parts like it in the library: the TLV1571CDW by Texas Instruments, the AD7472AR-REEL by Analog Devices, the AD7472YR by Analog Devices and the AD7472YRZ by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
