Questions
Is there a KiCad symbol and footprint for the INA849DGK?
Yes. The symbol is Amplifier_Instrumentation:INA849DGK 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 INA849DGK?
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the INA849DGK datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the INA849DGK?
JLCPCB lists it as part C4370731, with 2,198 in stock; the sellers' links on this page open their listings.
What can replace the INA849DGK?
Parts like it in the library: the COSINA333MRA by COSINE, the COSINA333MRB by COSINE, the AD8236ARMZ-R7 by Analog Devices and the AD8421ARMZ-R7 by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the INA849DGK?
