Abstract
In an AD converter, a first DAC circuit performs a first operation in parallel with a second operation performed by a second DAC circuit, and the first DAC circuit performs the second operation in parallel with the first operation performed by the second DAC circuit. In the first operation, electric charge corresponding to an input signal of the first DAC circuit or an input signal of the second DAC circuit is sampled. In the second operation, an AD conversion is sequentially performed on the basis of the electric charge sampled in the first operation. The first DAC circuit and the second DAC circuit alternately perform the first operation and the second operation.
