An AD converter evaluation apparatus evaluates an AD converter, which includes a first programmable power supply, a second programmable power supply, an attenuator circuit, an addition circuit, and a digital multimeter. The first and second programmable power supplies sets a first and second voltages. The attenuator circuit attenuates the first voltage of the second programmable power supply. The addition circuit adds the first voltage of the first programmable power supply and the attenuated voltage of the attenuator circuit. The digital multimeter measures the first voltage of the first programmable power supply and the second voltage of the second programmable power supply. Output voltage of the addition circuit is input to the AD converter.
