Abstract
A digital-to-analog converter (DAC) for converting a digital input word to an analog output signal includes a string DAC, a first interpolator and a second interpolator. The string DAC outputs a first voltage and a second voltage in response to M most significant bits of the digital input word. The first interpolator interpolates between the first and second voltages in response to middle Q least significant bits of the digital input word and provides a first interpolated voltage. The second interpolator interpolates between the first interpolated voltage and the second voltage in response to lower P least significant bits of the digital input word.
