Questions

Is there a KiCad symbol and footprint for the INA125U?

Yes. The symbol is EasyEDA_Cloud:INA125UA_2K5 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the INA125U?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the INA125U datasheet?

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

Where can I order the INA125U?

JLCPCB lists it as part C1346239, with 13 in stock; the sellers' links on this page open their listings.

What can replace the INA125U?

Parts like it in the library: the INA110KU by Texas Instruments, the INA125UA by Texas Instruments, the INA125UA/2K5 by Texas Instruments and the INA125U/2K5 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the INA125U?

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