Questions
Is there a KiCad symbol and footprint for the INA121UAE4?
Yes. The symbol is EasyEDA_Cloud:INA121UAE4 and the footprint Package_SO:SO-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 INA121UAE4?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the INA121UAE4 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the INA121UAE4?
JLCPCB lists it as part C4370641, with 0 in stock; the sellers' links on this page open their listings.
What can replace the INA121UAE4?
Parts like it in the library: the MAX4461TESA+ by Maxim Integrated (Analog Devices), the EL8172FSZ by Renesas Electronics, the INA118UB/2K5G4 by Texas Instruments and the INA118UBG4 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the INA121UAE4?
