Abstract
According to one embodiment, an AD conversion circuit of a pipeline type or successive-approximation type which compares an input voltage and a reference voltage to perform AD conversion is provided which comprises a reference voltage generating unit that generates the reference voltage. The reference voltage generating unit changes the reference voltage according to an analog-gain specifying value for setting a gain of an output value against the input voltage.
