MAX5774UCB+-MAX5774UTK+
32-Channel, 14-Bit, Voltage-Output DACs with Serial Interface
General DescriptionThe MAX5773/MAX5774/MAX5775 32-channel, 14-bit,
voltage-output, digital-to-analog converters (DACs) are
ideal for applications requiring a high number of pro-
grammable voltages. The MAX5773/MAX5774/
MAX5775 can be programmed to calibrate the 14-bit
input data word for gain and offset errors before updat-
ing the DAC output.
An SPI™-/QSPI™-/MICROWIRE™- or DSP-compatible
serial interface controls the MAX5773/MAX5774/
MAX5775. Each DAC channel has its own input, gain,
and offset register. These three registers pass data
through one of the two multiplier accumulator units
(MACs), resulting in a voltage output corrected for gain
and offset error. Each DAC channel has a double-
buffered input structure to minimize the digital-noise
feedthrough from the digital inputs to the outputs, and
allows for synchronous or asynchronous updating of
the outputs. The DAC outputs update independently or
simultaneously with a single software or hardware com-
mand. The MAX5773/MAX5774/MAX5775 also provide
a digital output (DOUT) that allows for readback or
daisy chaining of multiple devices.
All DAC outputs are buffered and drive 10kΩin parallel
with 100pF. The MAX5773 has a 0 to +10V output
range; the MAX5774 has a -2.5V to +7.5V output range;
and the MAX5775 has a -5V to +5V output range.
The MAX5773/MAX5774/MAX5775 are available in a
68-pin, 10mm x 10mm, TQFN package and a 64-pin,
12mm x 12mm, TQFP package. The MAX5773/
MAX5774/MAX5775 are specified over the 0°C to +85°C
temperature range. Refer to the MAX5753/MAX5754/
MAX5755 data sheet for similar 14-bit, 32-channel DACs
without offset and gain calibration.

Note 1:AVCCshould be at least 0.25V higher than the maximum output voltage required from the DAC.
Note 2:Linearity guaranteed for full code range.
Note 3:Offset error is measured at code 0. Gain error is measured at code 3FFFh.
Note 4:DC crosstalk is the change in the output level of one DAC at midscale in response to the full-scale output change of all other DACs.
Note 5: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 6: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.
Note 7:In DSP mode, maintain the maximum CSpulse width low to ≤16 SCLK cycles.

MAX5773/MAX5774/MAX5775
Detailed DescriptionThe MAX5773/MAX5774/MAX5775 are 32-channel, 14-
bit, voltage-output DACs. All devices accept a +3.0V
external reference input at REF. An internal offset DAC
allows all outputs to be offset up to -5V (see Table 1).
A 33MHz SPI-/QSPI-/MICROWIRE-or DSP-compatible
serial interface (see Figure 1) controls the
MAX5773/MAX5774/MAX5775. Use DSPto select the
DSP mode or the SPI/QSPI/MICROWIREmode.
Each DAC has a double-buffered input structure to
minimize the digital-noise feedthrough from the digital
inputs to the outputs. The two buffers are organized as
an input register followed by a DAC register. Input reg-
isters update the DAC registers independently or simul-
taneously with a single software or hardware command.
Each DAC channel has its own offset and gain registers
that calibrate offset and gain errors for a given channel.
The MAX5773/MAX5774/MAX5775 are divided into two
banks of 16 channels to provide real-time calibration of
channel pairs. Channel bank pairs are ordered as
(bank 0:bank 1) OUT0:OUT16, OUT1:OUT17 …
OUT14:OUT30, OUT15:OUT31.
An offset DAC allows all the outputs to be offset up to
-5V and dual ground-sensing inputs (GS1 and GS2)
allow the output voltages to be referenced to remote
