Abstract

Eine Digital-Analog-Umsetzer-Vorrichtung (DAC) umfasst zur Umsetzung eines digitalen Eingangssignals (D) in ein analoges Ausgangssignal (A) eine erste Einheit (F1, F2), zwei Digital-Analog-Umsetzer (DAC1, DAC2) und eine zweite Einheit (K1, K2), welche in der genannten Reihenfolge hintereinander geschaltet sind. Aus dem digitalen Eingangssignal (D) werden digitale Zwischensignale (D1, D2), welche in vorgegebenen Bereichen liegen, erzeugt. Diese werden in analoge Zwischensignale (A1, A2) umgesetzt, aus welchen sich durch eine Linearkombination das analoge Ausgangssignal (A) ergibt.
