protection on their reference inputs to satisfy absolute
maximum ratings. The MAX5734 features outputs that
are almost rail-to-rail. This allows the AV
supplies to be set to voltages within the absolute maxi-
mum ratings of the PEIC. This guarantees that the PEIC
is protected in all situations.
Additional protection is provided by the MAX5734
glitch-free power-up into the clear state with all DAC
outputs set to approximately 0V. Either the serial port or
the CLR input can assert the clear function.
Grounding and power-supply decoupling strongly influ-
ence device performance. Digital signals can couple
through the reference input, power supplies, and ground
connection. Proper grounding and layout can reduce

plies with an additional 0.1µF and 1µF on each pin, as
close to the device as possible. Refer to the MAX5732–
MAX5735 evaluation kit for a suggested layout.
The MAX5732–MAX5735 have four separate power
supplies. AV
(except for the output buffers) and DV
digital section of the device. AV

The MAX5732–MAX5735 feature an exposed paddle on
the backside of the package for improved power dissi-
pation. The exposed paddle is electrically connected to
V
that shares the same potential. For more information on
the exposed paddle QFN package, refer to the following
