Abstract: A parallel digital-analog converter for the conversion of a plurality of differential digital input signals into a differential analog output signal, including a group of 1-bit digital-analog converters (200) which respectively include an intermediate storage cell (202) and a current cell (201) and which are adapted to feed a respective output current to a first (204) or a second output contact (206) in dependence on a logic state of the intermediate storage cell, wherein a first of two outputs of an intermediate storage cell (202) is connected by way of an input resistor (220) to a first signal terminal (208.1) of a first transistor (208) and a second of the two outputs of the intermediate storage cell (202) is connected by way of an input resistor (218) to a first signal terminal (210.
