摘要：In a semiconductor integrated circuit (1), a digital-to-analogue converter (2)converts digital signals into analogue signals, and outputs differential analogue currentsignals respectively to positive and negative signal lines (AIP, AIN). A filter (4) filtersdifferential analogue signals input through the positive and negative signal lines. A first

resistance is connected between the positive signal line and a reference potential. Asecond resistance is connected between the negative signal line and the referencepotential. The first and second resistances have the function of converting the currentsignals flowing on the positive and negative signal lines, into voltage signals, and thefunction of an electronic volume control for controlling the DC component levels of thevoltage signals.
