    For the AD7997 / AD7998 If the ALERT/BUSY functionality is not being used can the ALERT/BUSY pin be left float or must it be tied high or low?  I see guidance here to tie the CONVST pin low if it will not be used but do not see anything specific to ALERT…

    I can't change channels on the AD7998, I get the same value 8 times. Can you
    give a recommended sequence to change channels over I2C?

    Hi All

    As a last resort, I looked to another IC.

    I have soldered the AD7998-0 ADC to a breakout board.

    Hello,

    In attempt to implement peak detection I'm trying to collect Max values using the AD7997 connected to an I2C bus operating at 156us/bit.

    Hi Sean,

    I measured the frequency using my Amprobe 37XR-A though I am questioning what I measured there as I'm not sure if measuring frequency is something only possible on AC circuits, it is possible that I had it mis-configured and thought I was reading…
