An object of the present invention is to provide a receiver, a digital-analog converter and a tuning circuit in which temperature compensating components can be formed on a semiconductor substrate while reducing component costs. An FM receiver 100 is constituted by including an antenna 1 , a high frequency receiving circuit 2 , a local oscillator 3 , two digital-analog converters (DACs) 4, 6 , a control section 8 , a mixing circuit 9 , an intermediate frequency amplification circuit 10 , a detection circuit 11 , a low frequency amplification circuit 12 and the speaker 13 . The DACs 4, 6 have a predetermined temperature coefficient, of which output voltage is changed in accordance with ambient temperature. When a characteristic of VCO 31 is changed with variations of ambient temperature so as to cause a control voltage applied to the VCO 31 to be changed, output voltages of the DACs 4, 6 are also changed similarly.
