The 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 10kΩ in 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.
