AMIC110: Pin behavier during reset

AMIC110: Pin behavier during RESET

Part Number: AMIC110

Hello all,

I am using the AMIC110.

Currently I am wondering about the AMIC pins hehavier during reset. Pin J17 should be low during power-on reset (according to datasheet SPRS971C -AUGUST 2016-REVISED DECEMBER 2018 p.30 ), but I measure a high (3.3V) during power-on reset. What do I need to do to keep pin J17 low during active reset?

With kind regards

Thomas

    Thomas, J17 should be low during POR as the datasheet states.  Are you sure there is not another device affecting the state of the signal during reset?  What is connected to that signal?

    Regards,

    James
