Abstract
Digital-to-analog converter having a reference voltage divider and a selection circuit by which the voltage at one of the nodal points of the reference voltage divider can be switched-through to the output of the converter. The selection circuit is controlled by selection signals coming from a decoder circuit by which the digital input signal is decoded. In addition, the converter includes a bias voltage divider which can apply different bias voltages to a level shifting circuit by which the signal level of the selection signals can be shifted.
