摘要：
A D/A converter includes a D/A conversion part for converting a digital input signal into an analog output signal, a parameter setting part for generating a plurality of circuit parameters which define a voltage range of the analog output signal, and a setting control part for selecting desired circuit parameters from the plurality of circuit parameters in accordance with data supplied from an external device, so that the D/A conversion part generates the analog output signal having a voltage based on the desired circuit parameters.
