A temperature compensated differential amplifier includes a first differential amplifier and a second differential amplifier. The first differential amplifier includes a feedback resistance, and has a gain proportional to temperature. The second differential amplifier is connected to the output side of the first differential amplifier, includes no feedback resistance, and has a gain inversely proportional to the temperature. The first differential amplifier carries out the temperature compensation of the gain and distortion of the second differential amplifier.
