ABSTRACT:
A digital to analog converter having an n-bit device for converting a 2n- digital word to analog form. The converter converts the first n bits of the digital word and stores the analog value in a first sample and hold circuit. The remaining n bits of the word are subsequently converted to analog form and stored in a second sample and hold circuit. The two stored samples are summed in proportion to predetermined weighting factors to produce the analog equivalent of the 2n-bit digital word.
