CIRCUIT FOR HIGH END AMPLIFIER OF COMPUTER

摘要

PURPOSE: A circuit for a high end amplifier of a computer is provided to improve response speed by performing first amplification through a semiconductor OP amp. CONSTITUTION: A circuit is comprised of a pre-amplifying stage and a push-pull circuit. The pre-amplifying stage is comprised of an OP amp(21). The push-pull circuit is connected to the output terminal of the pre-amplifying stage. The push-pull circuit is comprised of a non-inverting buffer amplifier and an inverting buffer amplifier. The output of the fourth tube and the third tube is comprised of the push-pull.
