  • Differential digital/analog converter
    Patent number: 6593868
    Abstract: A differential digital/analog converter for the conversion of a digital input value into an analog output voltage with a first current source group, which has a plurality of current sources comprising at least one p-MOS transistor, which can be switched to at least one current collecting line (11, 12) in dependence on the digital input value, the first current source group having a binary current source switching segment (4) comprising binary current sources (6), with a second current source group, which has a plurality of current sources comprising at least one n-MOS transistor, which can be switched to the current collecting line (11, 12) in dependence on the digital input value, the second current source group having a binary current source switching segment (5) comprising binary current sources (13), and with an output buffer (3) for the conversion of the current flowing on the at least one current collecting line (11, 12) into the analog output voltage.
