Abstract
A current output circuit includes a separation circuit that separates a digital pseudo sine wave into first and second digital pseudo half-waves, a first digital-to-analog (DA) converter that converts the first digital pseudo half-wave into a first analog half-wave signal, and a second DA converter that converts the second digital pseudo half-wave into a second analog half-wave signal. The pseudo sine wave is represented by a digital code having an n bit width, in which n is a natural number. The separation circuit includes a plurality of OR circuits that output a logical OR between a value of a most significant bit representing a code in the digital code and values of bits other than the most significant bit as the first pseudo half-wave.
