A digital-to-analog converter (DAC) with high linearity includes a switched capacitor amplifier removably coupled to a capacitor array. The result of the conversion by the capacitor array is sampled by the switched capacitor amplifier directly from the capacitor in the most significant cell in the array. The switched capacitor amplifier includes a memory capacitor and a feedback capacitor. The memory capacitor provides the initial output voltage corresponding to the result of the conversion when coupled to the capacitor array and stores the output voltage while the feedback capacitor is reset.
