Abstract

A digital-to-analog conversion arrangement for converting a digital input signal comprises first and second digital-to-analog converters (DACs) having different signal resolutions and a digital-to-analog converter selector for selecting the first DAC or the second DAC if the digital input signal has a power in a first or a second power range, respectively. The digital-to-analog conversion arrangement further comprises an analog signal merger for merging a first analog signal and a second analog signal, the first analog signal being based on a first analog output signal of the first digital-to-analog converter and the second analog signal being based on a second analog output signal of the second analog-to-digital converter. A corresponding method for digital-to-analog conversion of a digital input signal and a computer readable digital storage medium are also described.
