Is there a KiCad symbol and footprint for the AD7661AST?
Yes. The symbol is EasyEDA_Cloud:AD7666AST and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD7661AST?
LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.
Where is the AD7661AST datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD7661AST?
JLCPCB lists it as part C7453429, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD7661AST?
Parts like it in the library: the AD7671ASTZ by Analog Devices, the ADS7882IPFBR by Texas Instruments, the AD7610BSTZ by Analog Devices and the AD7622BSTZRL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
