CMOS 8-IBit DAG with Output Amplifier
General Description
The MX7224 is a precision voltage-output CMOS
digital-to-analog converter (DAC) which includes an
output amplifier on chip. Only an external reference
source is required for operation and the fully specified
accuracy is achieved with no external trims.
Double buffered interface logic is included to allow
simultaneous updating in systems which have several
D_ACc_hanneIs in operation, Control is provided by
CS. WR, and LDAC (Load DAC) inputs. A RESET
Input 15 provided which acts as a zero override. All
logic inputs are compatible with TTL and 5V CMOS
logic levels.
Specified Performance is guaranteed for reference
inputs ranging from +2V to +12.5V when using dual
supplies. With a +10V reference the performance is
also specified for single supply operation. The DAC
output can drive +10V into a 2kQ load.

The output may be shorted to AGND provided that the power dissipation of the package is not exceeded. Typical short circuit current to
AGND is 25mA.
