ISO7721-Q1: Short primary GND and secondary GND

Part Number: ISO7721-Q1

Hi team,

Can we short primary GND and secondary GND if we don't need isolation?


  • Hello,

    Thank you for your question.

    Yes, your understanding is correct. The GND pins on both sides of the ISO7721-Q1 can be shorted in order to bypass the isolation barrier.

    The main function of the ISO7721-Q1 is to provide isolation. if isolation is not required, then this device is not needed.
