An OTA circuit includes a first input stage that includes a first pair of transistors having sources coupled to a reference potential and converts a differential input voltage input to gates of the first pair of transistors into a first control current, a second input stage that includes a second pair of transistors having sources coupled to the reference potential and converts the differential input voltage input to gates of the second pair of transistors into a second control current, a first output circuit that generates one output current out of the differential output currents in accordance with the first control current, and a second output circuit that generates the other output current out of the differential output currents in accordance with the second control current.
