INA214: Inquire P2P high voltage solution

Part Number: INA214

Hi Sir,

May I learn from you that do we have a solution P2P with INA214 and can support at least 54V?

Thank you for your kindly help.

  • Hello Edward,
    Thanks for reaching out on the forum. I am not sure what you mean by p2p. As for a TI-design, there are not any that I am aware. Some people may attempt to use a voltage divider between the shunt resistor and the device, but we typically advise against that. Why not use the INA240? It comes in a 100V/V gain, has a lower offset, and can handle up to 80V common mode without any supporting workaround chips.

    Hi Patrick,

    Sorry for misunderstanding, P2P means Pin to Pins solution, 

    Do we have a solution Pin to Pin with INA214 and can support at least 54V?

    Thank you.

    Hello user4773172,

    Unfortunately we do not. The closest we have is the INA190, which can handle a common mode of 40V.
