MAX5735AUTN+-MAX5735BUTN+
32-Channel, 16-Bit, Voltage-Output DACs with Serial Interface
General Description
The MAX5732–MAX5735 are 32-channel, 16-bit, voltage-
output, digital-to-analog converters (DACs). All devices
accept a 3V external reference input. The devices
include an internal offset DAC that allows all the outputs
to be offset and a ground-sensing function, allowing out-
put voltages to be referenced to a remote ground.
A 33MHz SPI™-/QSPI™-/MICROWIRE™- and digital
signal processor (DSP)-compatible serial interface con-
trols the MAX5732–MAX5735. Each DAC has a double-
buffered input structure that helps minimize the digital
noise feedthrough from the digital inputs to the outputs,
and allows for synchronous or asynchronous updating
of the outputs. The MAX5732–MAX5735 also provide a
DOUT that allows for read-back or daisy chaining multi-
ple devices. The devices provide separate power
inputs for the analog and digital sections and provide
separate power inputs for the output buffer amplifiers.
The MAX5732–MAX5735 include proprietary deglitch
circuits to prevent output glitches at power-up and
eliminate the need for power sequencing. The devices
provide a software-shutdown mode to allow efficient
power management. The MAX5732–MAX5735 con-
sume 50µA of supply current in shutdown.
The MAX5732–MAX5735 provide buffered outputs that
can drive 10kΩin parallel with 100pF. The MAX5732 has
a 0 to +5V output range; the MAX5733 has a 0 to +10V
range; the MAX5734 has a -2.5V to +7.5V range; the
MAX5735 has a -5V to +5V range. The MAX5732–
MAX5735 are available in a 56-pin, 8mm x 8mm, thin
QFN package and 64-pin TQFP package and operate
over the 0°C to +85°C temperature range.

Zero-scale error is measured at code 0. Full-scale error is measured at code FFFFhex.
Note 5:
DC crosstalk is the change in the output level of one DAC at zero or full scale in response to the full-scale output change of all
other DACs.
Note 6:
Digital feedthrough is a measure of the impulse injected into the analog outputs from the digital control inputs when the
device is not being written to. It is measured with a worst-case change on the digital inputs.
Note 7:
Digital crosstalk is the glitch impulse transferred to the output of one DAC at midscale while a full-scale code change is written
into another DAC.
Note 8:
DAC-to-DAC crosstalk is the glitch impulse that appears at the output of one converter due to both the digital change and
subsequent analog output change at another converter.
