Abstract
A digital-to-analog converter includes an amplifier including at least two input terminals corresponding to a non-inverting input terminal; and a chopping unit performing a chopping operation between voltages provided to the at least two input terminals corresponding to the non-inverting input terminal. The digital-to-analog converter has an X+Y bit structure and removes an offset by performing an interpolation chopping operation and/or a main buffer chopping operation at the same time. The digital-to-analog structure can be embodied in a small area and can process high bit image data.
