DAC Continuous Conversion Mode
Once the DAC is configured in continuous conversion
mode, the analog output, OUT, is updated at the rising
edge of every eighth clock pulse (Figure 7). To exit
DAC continuous conversion mode, toggle CS. The
device requires a new control word before any further
conversions take place.
ADC Continuous Conversion Mode
Set C0 = 1 to select continuous conversion mode. The
falling edge of SCLK after the eighth bit of the control
word causes the ADC to switch from track to hold
mode and begin conversion. To avoid corruption of the
conversion result, SCLK must be disabled for 36s
(Figure 8). After completing the conversion, the ADC
automatically returns to track mode, and the next eight
clock cycles shift out the result on DOUT. The falling
edge of SCLK during the eighth bit of the result will
again cause the ADC to switch from track to hold mode
and begin the next conversion.
