32-Channel, 16-Bit, Voltage-Output
DACs with Serial Interface
General Description
The MAX5762–MAX5765 32-channel, 16-bit, voltage-
output, digital-to-analog converters (DACs) are ideal for
applications requiring a high number of programmable
voltages. The MAX5762–MAX5765 can be programmed
to calibrate the 16-bit input data word for gain and off-
set errors before updating the DAC output.
An SPI™-/QSPI™-/MICROWIRE™- or DSP-compatible
serial interface controls the MAX5762–MAX5765. 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 volt-
age output corrected for gain and offset error. Each DAC
channel has a double-buffered input structure to mini-
mize the digital-noise feedthrough from the digital inputs
to the outputs, and allows for synchronous or asynchro-
nous updating of the outputs. The DAC outputs update
independently or simultaneously with a single software or
hardware command. The MAX5762–MAX5765 also pro-
vide 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 MAX5762 has a 0 to +5V output range;
the MAX5763 has a 0 to +10V output range; the MAX5764
has a -2.5V to +7.5V output range; and the MAX5765 has
a -5V to +5V output range.
The MAX5762–MAX5765 are available in a
68-pin, 10mm x 10mm, TQFN package and a 64-pin,
12mm x 12mm, TQFP package. The MAX5762–
MAX5765 are specified over the 0°C to +85°C tempera-
ture range. Refer to the MAX5732–MAX5735 data sheet
for similar 16-bit, 32-channel DACs without offset and
gain calibration.
