MX7224:CMOS, Double-Buffered, 8-Bit DAC with Voltage-Output Amplifier

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 channels in operation. Control is provided by active-low CS, active-low WR, and active-low LDAC (Load DAC) inputs. An active-low 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 2kΩ load.
