Questions

Is there a KiCad symbol and footprint for the INA819ID?

Yes. The symbol is EasyEDA_Cloud:SGM621XMS8G_TR 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 INA819ID?

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

Where is the INA819ID datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the INA819ID?

JLCPCB lists it as part C2060451, with 85 in stock; the sellers' links on this page open their listings.

What can replace the INA819ID?

Parts like it in the library: the INA821ID by Texas Instruments, the INA849D by Texas Instruments, the AD8421BRZ-R7 by Analog Devices and the INA818ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the INA819ID?

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