Abstract

PURPOSE:To make it possible to obtain easily outputs differing output level and output impedance by an amplifier with output terminals, by connecting a feedback resistance to the voltage-division part of resistances connected between the amplifier and one output terminal. CONSTITUTION:At the output side of operational amplifier 1, output terminal T1 is provided through feedback or level-adjusting resistance R3 and output-impedance-matching resistance R4, and output terminal T2 through output-impedance- matching resistance R5. To the voltage division part of resistances between output terminal T1 and amplifier 1, feedback resistance R2 of amplifier 1 is connected.
