3 Description
The DAC7750 and DAC8750 (DACx750) are lowcost,
precision, fully-integrated, 12-bit and 16-bit
digital-to-analog converters (DACs) designed to
meet the requirements of industrial process-control
applications. These devices can be programmed as
a current output with ranges of 4 mA to 20 mA, 0 mA
to 20 mA, or 0 mA to 24 mA. The DACx750 include
reliability features such as CRC error checking on
the SPI frame, a watchdog timer, an open circuit,
compliance voltage, and thermal alarm. In addition,
the output current can be monitored by accessing an
internal precision resistor.
These devices include a power-on-reset function
designed to power up the device in a known state
(IOUT is disabled and in a Hi-Z state). The CLR pin
sets the current output to the low end of the range
if the output is enabled. Program the zero and gain
registers to digitally calibrate the device in the end
system. The output slew rate is also programmable by
register. These devices can superimpose an external
HART® signal on the current output, and operate with
a 10-V to 36-V supply.
