    Hi switch,

    Couple of things:

    1) For the Inputs 3 and 4, I believe you're planning to configure them as ac-coupled, single-ended inputs. however, the IN3M and IN4M cannot be left floating for the same. Pelase refer to the recommended connections in datasheet for ac-coupled, single-ended inputs:

    2) Is the AVDD = 3.3V?

    3) Are the I/O input logic levels per the IOVDD given to the device?

    4) Since SCL/SDA is an open-drain I2C input, is there a pull-up resistor in the path?

    Thanks and Regards,
