Abstract: A digital-to-analog converter of the R/2R ladder type is composed of two individually asymmetric ladders symmetrically coupled to a differential amplifier. Switch means in the shunt arms of the ladders are controlled so that the same number of shunt arms are connected to each of a pair of input or output nodes irrespective of the value of the controlling digital signal. The most significant shunt arm in each ladder may be configured as an equivalent of that part of the respective ladder extending from the respective stage node towards the least significant end of the ladder.
