Serial Interface
MAX5753/MAX5754/MAX5755
The MAX5753/MAX5754/MAX5755 are 32-channel, 14-
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, allow-
ing output voltages to be referenced to a remote ground.
A 33MHz SPI™-/QSPI™-/MICROWIRE™- and digital sig-
nal processor (DSP)-compatible serial interface controls
the MAX5753/MAX5754/MAX5755. Each DAC has a
double-buffered input structure that helps minimize the
digital noise feedthrough from the digital inputs to the out-
puts, and allows for synchronous or asynchronous updat-
ing of the outputs. The MAX5753/MAX5754/MAX5755
also provide a DOUT that allows for read-back or daisy
chaining multiple devices. The devices provide separate
power inputs for the analog and digital sections and pro-
vide separate power inputs for the output buffer ampli-
fiers. The MAX5753/MAX5754/MAX5755 include pro-
prietary 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
MAX5753/MAX5754/MAX5755 consume 50µA of supply
current in shutdown.
The MAX5753/MAX5754/MAX5755 provide buffered out-
puts that can drive 10kΩ in parallel with 100pF. The
MAX5753 has a 0 to +10V range; the MAX5754 has a
-2.5V to +7.5V range; the MAX5755 has a -5V to +5V
range. The MAX5753/MAX5754/MAX5755 are available
in 56-pin, 8mm x 8mm, thin QFN or 64-pin thin QFP
packages and operate over the 0°C to +85°C tempera-
ture range.
