Is there a KiCad symbol and footprint for the INA240A3D?
Yes. The symbol is Amplifier_Current:INA240A3D 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 INA240A3D?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the INA240A3D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the INA240A3D?
JLCPCB lists it as part C2060584, with 1,622 in stock; the sellers' links on this page open their listings.
What can replace the INA240A3D?
Parts like it in the library: the INA219AID by Texas Instruments, the INA240A1D by Texas Instruments, the CSA240LCSOIC8 by analogysemi and the MAX4080TASA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the INA240A3D?
7 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
