Questions

Is there a KiCad symbol and footprint for the ADA4891-2ARMZ-R7?

Yes. The symbol is EasyEDA_Cloud:ADA4891-2ARMZ-R7 and 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 ADA4891-2ARMZ-R7?

MSOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the ADA4891-2ARMZ-R7 datasheet?

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

Where can I order the ADA4891-2ARMZ-R7?

JLCPCB lists it as part C143927, with 2,155 in stock; the sellers' links on this page open their listings.

What can replace the ADA4891-2ARMZ-R7?

Parts like it in the library: the RS358AXM by Jiangsu RUNIC Tech, the WS72052M-8/TR by WILLSEMI, the AD8616ARMZ-REEL by Analog Devices and the CBM8052AMS8 by Corebai Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
