Questions

Is there a KiCad symbol and footprint for the AD7841AS?

Yes. The symbol is EasyEDA_Cloud:AD7841AS and the footprint generated:QFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AD7841AS?

MQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.

Where is the AD7841AS datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD7841AS?

JLCPCB lists it as part C5548551, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AD7841AS?

Parts like it in the library: the AD7839ASZ-REEL by Analog Devices, the AD1954YS by Analog Devices, the AD1954YSRL by Analog Devices and the AD7835ASZ-REEL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the AD7841AS?

2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
