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
DAC Jirpannelsjtgtperation. Control is provided by
CS, WR. and LDAC (Load DAC) inputs. A RESET
input is 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 2k0 load.
