Questions
Is there a KiCad symbol and footprint for the AD644KH?
Yes. The symbol is EasyEDA_Cloud:AD647KH and the footprint EasyEDA_Cloud:TO-99-8_TI_LMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD644KH?
TO-99, with 8 pins. Its footprint is drawn on this page.
Where is the AD644KH datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD644KH?
JLCPCB lists it as part C4370253, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD644KH?
Parts like it in the library: the AD542LH by Analog Devices, the AD542SH by Analog Devices, the AD544JH by Analog Devices and the AD544LH by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
