Abstract
Provided is a current output circuitincluding a pseudo sine wave separation circuitthat separates a pseudo sine wave represented by a digital code Din into two pseudo half-waves represented by digital signals Dand D, a DA converterthat converts the pseudo half-wave represented by the digital signal Dinto an analog half-wave signal V, a DA converterthat converts the pseudo half-wave represented by the digital signal Dinto an analog half-wave signal V, and a voltage-current conversion circuitthat converts voltages of the half-wave signals Vand Vinto currents and outputs a current Iout obtained by combining the currents.
