  • Patent number: 8907830
    Abstract: A digital-to-analog converter for converting digital values to an analog output signal includes a first converter section and a second converter section operating at different conversion rates. A first analog signal provided by the first converter section and a second analog signal provided by the second converter section are combined to obtain the analog output signal. The concept may be used in fields of DAC applications where the sample rate is much higher than the signal bandwidth. The limited signal bandwidth means that the maximum change between two neighboring samples is a small fraction of the whole DAC range. The first converter section may cover a large range of values, whereas for the second converter section a relatively small range of values may be sufficient.
