Is there a KiCad symbol and footprint for the AD7921ARM?
Yes. the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD7921ARM?
MSOP-8, with 5 pins. Its footprint is drawn on this page.
Where is the AD7921ARM datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD7921ARM?
JLCPCB lists it as part C7453460, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AD7921ARM?
Parts like it in the library: the AD7276ARMZ-REEL by Analog Devices, the AD7683BRMZRL7 by Analog Devices, the ADS8326IDGK by Texas Instruments and the MCP3551-E/MS by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
