DAC1218 12-Bit Binary Multiplying D/A Converter

The DAC1218 and the DAC1219 are 12-bit binary 4-quadrant multiplying D to A converters The linearity differential non-linearity and monotonicity specifications for these converters are all guaranteed over temperature In addition these parameters are specified with standard zero and fullscale adjustment procedures as opposed to the impractical best fit straig.
