- Provided is an analog digital converting device which consumes a low power and guarantees fast operation characteristic. The analog digital converting device includes a sub-ADC and a successive approximation ADC. The sub-ADC converts an external analog signal into a first digital signal by using first and second reference voltages. The successive approximation ADC comprises a plurality of bit streams, and converts the external analog signal into a second digital signal according to a successive approximation operation using the first and second reference voltages. The successive approximation ADC receives the first digital signal, and converts the second digital signal in a state where one of the first and second reference voltages has been applied to the bit streams based on the first digital signal.
