<p>An improved analog to digital converter is provided in which high and low order bytes of the digital output can be sequentially generated by a single flash converter circuit. Upon the generation of the high order byte, a high byte equivalent voltage is subtracted from the analog input voltage and the residual is multiplied by a predetermined factor. The resultant product signal is converted by the same flash converter circuit to the low order byte. In addition, the low scale and full scale of the converter inputs may be programmed to have the same polarity as, or the opposite polarity of, the polarities of the reference voltages.</p> |
