Abstract
In a digital-to-analog converter having means to convert a digital input signal into an analog signal, processing means to evaluate an error attendant upon the conversion, and memory means to store the evaluated error; a digital-to-analog converter with a compensating circuit wherein the processing means comprises a ramp voltage generator, a clock pulse generator, and counting means to count clock pulses of the generator and to deliver the error on the basis of the count value of the clock pulses at each time when the ramp voltage exceeds the output of the conversion means.
