Circuit for preventing crosstalk

摘要

An operational amplifier is applied with an audio signal at a non-inverting terminal thereof for amplifying the audio signal. A crosstalk cancelling circuit is provided for reducing the output of the operational amplifier to a level of crosstalk generated at the non-inverting terminal. The output of the crosstalk cancelling circuit is applied to an inverting terminal of the operational amplifier so as to cancel the crosstalk.
