nected to ground through a 1kΩ or 100kΩ (default)
resistor for each DAC. The third shutdown (shutdown 1)
command leaves the DACs outputs high impedance.
Table 2 lists the three shutdown modes of operation as
well as the power-up command.

The DOUT (MAX5306) follows DIN with a 16 clock
cycle delay. The DOUT is capable of driving 20pF load
with a 50ns (max) delay from the falling edge of SCLK.
DOUT is primarily used for daisy-chaining multiple
devices. Optionally, DOUT can be used to monitor the
serial interface for valid communications by connecting
DOUT to a microprocessor input.

Power-Up individual DAC
buffers indicated by data in
DAC1 through DAC8. A one
indicates the DAC output is
active. A zero does not affect
the DACs present state.
Shutdown individual DAC
buffers indicated by data in
DAC1 through DAC8. A one
indicates the DAC output is
high-impedance. A zero does
not affect the DACs present
state.
Shutdown individual DAC
buffers indicated by data in
DAC1 through DAC8. A one
indicates the DAC is shutdown
and the output is connected to
GND through a 1kΩ resistor. A
zero does not affect the DACs
present state.
