Abstract
A differential amplifier includes a first differential pair with one of an input pair serving as a first input terminal, a second differential pair with one of an input pair serving as a second input terminal, connected in parallel with the first differential pair and having the same conductivity type as the first differential pair, and a first capacity reduction circuit that reduces a capacity of the first differential pair in operation when a first input voltage input to the first input terminal is equal to or higher than an operation threshold of the first differential pair and a second input voltage input to the second input terminal is lower than an operation threshold of the second differential pair.
