Is there a KiCad symbol and footprint for the AD8226ARZ-R7?
Yes. The symbol is agg-kicad:AD8226 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AD8226ARZ-R7?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the AD8226ARZ-R7 datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD8226ARZ-R7?
JLCPCB lists it as part C34250, with 1,024 in stock; the sellers' links on this page open their listings.
What can replace the AD8226ARZ-R7?
Parts like it in the library: the INA821ID by Texas Instruments, the INA826AID by Texas Instruments, the INA849D by Texas Instruments and the INA828ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the AD8226ARZ-R7?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
