AD5541A
DECODING MULTIPLE DACS
The CS pin of the AD5541A can be used to select one of a
number of DACs. All devices receive the same serial clock and
serial data, but only one device receives the CS signal at any one
time. The DAC addressed is determined by the decoder. There is
some digital feedthrough from the digital input lines. Using a
burst clock minimizes the effects of digital feedthrough on the
analog signal channels.
Figure 35
shows a typical circuit.
