Abstract
A digital-to-analog conversion system includes a digital-to-analog converter and an output stage for converting an output signal of the digital-to-analog converter into a voltage range. The output stage includes a first amplifier including a first input for receiving the output signal of the digital-to-analog converter, a first resistance element coupled between a second input and an output of the first amplifier, a second resistance element coupled between the second input of the first amplifier and a ground reference, and a third resistance element switchably coupled from the second input of the first amplifier to an offset voltage.
