    Part Number: ADC3644 Hi team, I use the ADC3644 with an external 1.6V reference. I attach the waveforms of each power supply and VREF. It will take some time for VREF to stabilize, but is there any problem as long as each power supply and VREF are stabilized…

    Resolved
    Part Number: ADC3644 I'm having trouble understanding how the output bit mapper works. On page 38 of the ADC3644 data sheet, figure 8-37, gives you an example of the output mapping. The output on the right has an example cell of D0A (0x63, 0x54). I understand…
