Is there a KiCad symbol and footprint for the AD9742AR?
Yes. The symbol is EasyEDA_Cloud:AD9742ARRL and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD9742AR?
SOIC-28, with 28 pins. Its footprint is drawn on this page.
Where is the AD9742AR datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD9742AR?
JLCPCB lists it as part C7459449, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD9742AR?
Parts like it in the library: the DAC900U/1K by Texas Instruments, the AD9742ARZ by Analog Devices, the AD9754ARZ by Analog Devices and the DAC7625UB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
