ABSTRACT:
A digital-to-analog converter generates a voltage from power supply and ground voltages, generates upper and lower limit reference voltages for a reference width which regards the generated voltage as an intermediate potential, converts a change in an analog input signal with respect to the upper and lower limit reference voltages into a digital code, and performs a control in order to achieve a sample and hold of the analog input signal.
