The device provides the high and low level stages for one channel of a Dolby C-type NR system, including NR ON/OFF switching and all electronic switching necessary for Dolby C-type systems. In addition the TEA0665 includes a preamplifier for the record and playback functions and a multiplex buffer amplifier. The circuit offers two different line-output levels (−6 and 0 dBm) and a low-pass filter, which can be fed into the signal path in playback mode.

Features
