MAX5753/MAX5754/MAX5755
32-Channel, 14-Bit, Voltage-Output
DACs with Serial Interface
14
______________________________________________________________________________________
Detailed Description
The MAX5753/MAX5754/MAX5755 are 32-channel, 14-
bit, voltage-output DACs (Figure 1). The devices accept
a 3V external reference input at REF. An internal offset
DAC allows all outputs to be offset (see Table 1). The
devices provide a ground-sensing function that allows
the output voltages to be referenced to a remote ground.
A 33MHz SPI-/QSPI-/MICROWIRE-/DSP-compatible serial
interface controls the MAX5753/MAX5754/MAX5755
(Figure 2). Each DAC includes a double-buffered input
structure to minimize the digital noise feedthrough from
the digital inputs to the outputs, and allows for synchro-
nous or asynchronous updating of the outputs. The two
buffers are organized as an input register followed by a
DAC register that stores the contents of the output. Input
registers update the DAC registers independently or
simultaneously with a single software or hardware com-
mand. The MAX5753/MAX5754/MAX5755 also have a
DOUT that allows for read-back or daisy chaining multi-
ple devices.
The MAX5753/MAX5754/MAX5755 analog and digital
sections have separate power inputs. Separate power
inputs are also provided for the output buffer amplifiers.
Proprietary deglitch circuits prevent output glitches at
power-up and eliminate the need for power sequenc-
ing. A software-shutdown mode allows efficient power
management. The MAX5753/MAX5754/MAX5755 con-
sume 50A of supply current in shutdown.
All DACs provide buffered outputs that can drive 10k
in
parallel with 100pF. The MAX5753 has a 0 to +10V out-
put range; the MAX5754 has a -2.5V to +7.5V output
range; and the MAX5755 has a -5V to +5V output range.
External Reference Input (REF)
The REF voltage sets the full-scale output voltage for all
32 DACs. REF accepts a +3V ±3% input. Reference
voltages outside these limits can result in a degradation
of device performance.
REF is a buffered input. The typical input impedance is
10M
, and it does not vary with code. Use a high-
accuracy, low-noise voltage reference such as the
MAX6126AASA30 (3ppm/°C temp drift and 0.02% initial
accuracy) to improve static accuracy. REF does not
accept AC signals.
Ground Sense (GS)
The MAX5753/MAX5754/MAX5755 include a GS that
allows the output voltages to be referenced to a remote
ground. The GS input voltage range (VGS) is -0.5V to
+0.5V. VGS is added to the output voltage with unity
gain. The resulting output voltage must be within the
valid output-voltage range set by the power supplies.
See the Output Amplifiers (OUT0–OUT31) section for
the effect of the GS inputs on the DAC outputs.
Offset DAC
The MAX5753/MAX5754/MAX5755 feature an offset
DAC that determines the output voltage range. While
each part number has an output voltage range associ-
ated with it, it is the offset DAC that determines the end-
point voltages of the range. Table 1 shows the offset
DAC code required during power-up.
