HIGH-RESOLUTION DIGITAL-TO-ANALOG CONVERTER

摘要

A digital-to-analog converter (DAC) for converting a digital input signal (D) to an analog output signal (A) comprises a first unit (F1, F2), two digital-to-analog converters (DAC1, DAC2) and a second unit (K1, K2) which are connected in series in the above-mentioned order. Intermediate digital signals (D1, D2) that lie in predetermined bands are produced from the digital input signal (D). Said intermediate digital signals are converted to intermediate analog signals (A1, A2) from which the analog output signal (A) is obtained by linear combination.
