Questions

Is there a KiCad symbol and footprint for the INA849D?

Yes. The symbol is Amplifier_Instrumentation:INA849D 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 INA849D?

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

Where is the INA849D datasheet?

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

Where can I order the INA849D?

JLCPCB lists it as part C2871861, with 3,612 in stock; the sellers' links on this page open their listings.

What can replace the INA849D?

Parts like it in the library: the AD8421BRZ-R7 by Analog Devices, the AD8421ARZ-R7 by Analog Devices, the AD620ARZ-REEL(TOKMAS) by Tokmas and the AD620ARZ-REEL7(TOKMAS) by Tokmas. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the INA849D?

6 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
