ABSTRACT:
A circuit for converting an asymmetrical input signal applied to a single ended input terminal of the circuit to a symmetrical output voltage appearing across balanced differential outputs. The circuit includes first and second operational amplifiers, the outputs of which are the outputs of the circuit. The noninverting inputs of the two amplifiers being coupled to a reference voltage. The inverting input of the first amplifier being adapted to receive the input signal and further being coupled through a first resistor to the output thereof. The inverting input of the second amplifier being coupled both to the output thereof and the output of the first amplifier through respective second and third resistors.
