Abstract

PURPOSE:To obtain a balanced output and an unbalanced output by dividing voltages of the output signal having the same phase as an input signal and the output signal having the opposite phase and controlling gains of amplify ing circuits based on divided voltages. CONSTITUTION:A hot terminal TM and a cold terminal TC are connected by voltage dividing resistances R45 and R46 having a resistance value R9. The output voltage of an operational amplifier 21 corresponding to the differential voltage between the divided voltage and the earth potential is outputted to operational amplifiers 2 and 3 through input resistances R43 and R44 to control their output levels. A resistance value R4 of the resistance R43, a resistance value R0 of a resistance R41, and a resistance value Rh of a feedback resistance R47 are set to satisfy relations (R0.Rh)/(R4.R9)=1/2, thereby obtaining the inter-terminal voltage whose output level is equal between unbalance and balance.
