Abstract:
Provided is a D/A conversion device that more precisely reduces second harmonic distortions with a simple configuration. Specifically provided is a D/A conversion device comprising: a D/A conversion unit that receives input of a reference voltage and a digital value and then outputs an analog signal corresponding to the digital value on the basis of the reference voltage; and a superimposition unit that superimposes a superimposition signal based on the analog signal output by the D/A conversion unit onto the reference voltage. Also provided is a D/A conversion method. The D/A conversion device may further comprise a setting input unit to which is input a setting regarding at least one of a superimposition amount and a code of the analog signal included in the superimposition signal. The present invention also provides an adjustment device and an adjustment method for adjusting the D/A conversion device.
