Circuit Work Mention of the balanced output, people tend to immediately think of adding OP amplifier at the output of the positive-phase amplifier to be the inverting amplifier circuit, inverting the normal phase and the invert phase make up the balanced output. In the DC circuit, although this method can be used, but if it is broadband signal, phase shift of inverting amplifier is a problem. The drift of the OP amplifier A1 and A2 is equal in this circuit, so even if the input frequency changes,it won't happen phase distortion.
