From an audio signal, this circuit gets two signals of the same amplitude and opposite phases. This setting is widely used in bridge amplifiers (BTL). Transistors may be commonly used as BC series.
This anti-ringing circuit was found in an English documentation from 1996. The integrated circuit is...
