Is there a KiCad symbol and footprint for the AD8420ARMZ?
Yes. The symbol is EasyEDA_Cloud:AD8420ARMZ-RL 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 AD8420ARMZ?
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the AD8420ARMZ datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the AD8420ARMZ?
JLCPCB lists it as part C652809, with 7 in stock; the sellers' links on this page open their listings.
What can replace the AD8420ARMZ?
Parts like it in the library: the COSINA333MRA by COSINE, the COSINA333MRB by COSINE, the INA821IDGK by Texas Instruments and the INA849DGK by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the AD8420ARMZ?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
