  • Hi User5214405,

    It is possible that the PDWN pin does not have a good connection.  This pin must be pulled logic high for the device to convert.  Also, you must have a good clock source either from the crystal or externally derived clocking source.  If this clock source is intermittent or stops, conversion will also stop.

    Best regards,

    Bob B
