ABSTRACT:
An integrated circuit device includes an amplifier circuit that includes first to Nth amplifiers that are cascaded and receives an input signal, an A/D converter that performs an A/D conversion process on a signal amplified by the amplifier circuit, first to Nth D/A converters that are provided corresponding to the first to Nth amplifiers and used to perform an offset adjustment of the first to Nth amplifiers, and a control circuit that sets an offset adjustment of the first to Nth amplifiers using the first to Nth D/A converters and a gain adjustment of the first to Nth amplifiers.
