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 10kΩ in 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.
