Read-Data Format
The MAX5732–MAX5735 support daisy-chain connec-
tions of multiple devices. The default (power-up) config-
uration for the MAX5732–MAX5735 assumes that the
device may be part of a daisy chain of devices. DOUT
follows DIN after 32 clock cycles. For a read command,
DOUT provides read data (instead of the data value
shifted in) in the next cycle following a
CS
rising edge.
Figures 5 and 6 show examples of daisy-chain
data sequences.
Shutdown Mode
The MAX5732–MAX5735 feature a software-controlled
low-power shutdown mode. When bit 11 of the configu-
ration register is a logic high, the analog section of the
device is disabled, and the outputs go high impedance.
In shutdown, supply current is reduced to 50μA. Data
stored in the DAC and input registers is retained, and
the device outputs return to their previous values when
the device is brought out of shutdown. The serial inter-
face remains active while the device is in shutdown.
Power-Up State
The MAX5732–MAX5735 monitor the four power supplies
and maintain the output buffers in a known state until suffi-
cient voltage is available to ensure that no output glitches
occur. Once the minimum voltage threshold has been
passed, the device outputs come up in the clear state (all
outputs = 0). For proper power sequencing, V
SS
must be
applied first. Power sequencing is not necessary if V
SS
is
connected to AGND.
