Figure 12. Daisy-Chaining Multiple Devices with the Digital I/Os DIN/DOUT

Daisy-Chaining Devic es
Any number of MAX5120/MAX5121s can be daisy-
chained simply by connecting the serial data output pin
(DOUT) of one device to the digital input pin (DIN) of
the following device in the chain (Figure 12).
Another configuration allows several MAX5120/
MAX5121 DACs to share one common DIN signal line
(Figure 13). In this configuration, the data bus is com-
mon to all devices; data is not shifted through a daisy-
chain. However, more I/O lines are required in this
configuration, because each IC needs a dedicated
CS
line.
