ABSTRACT:
A digital-to-analog converter that includes pairs of positive and negative current sources that are connected through switches to two differential output lines. The switches are controlled as a function of a digital data. Each pair of current sources includes a pair of transistors of an output stage of a transconductance amplifier. The transconductance amplifier receives a reference voltage at a non-inverting input, and receives at an inverting input, the voltage at the middle node of a bridge of resistors that is connected between the two differential out-put lines. The output of the converter is the voltage between the two differential output lines.
