Abstract
A high-order converter generates a first high-order voltage Vand a second high-order voltage Vthat monotonously change with mutually opposite polarities with respect to high-order m bits (1≤m<n) of the digital signal. A low-order converter generates a first low-order voltage and a second low-order voltage that monotonously change with mutually opposite polarities with respect to low-order (n−m) bits of the digital signal. A first amplifier receives one of the first and the second high-order voltages and one of the first and the second low-order voltages to output one differential analog signal. Having a configuration in common with the first amplifier, a second amplifier receives another of the first and the second high-order voltages and another of the first and the second low-order voltages to output another differential analog signal.
