DESCRIPTION

The TDA7335 is a monolithic BICmos IC designed for use in stereo cassette player systems.

The device includes two separate audio channels composed by low noise preamplifier, Dolby B noise reduction system and Audio Music Sensor.

The dual preamplifier contains mute, autoreverse, metal/normal facilities for amplification of low level signal in applications requiring very low noise performances.

Each channel consists of two cascaded operational amplifiers.
