DESCRIPTION
The TDA7335 is a monolithic BICmos IC de-
signed for use in stereo cassetteplayer systems.
The device includes two separate audio channels
composed by low noise preamplifier, Dolby B
noise reductionsystemand Audio Music Sensor.
The dual preamplifier contains mute, autoreverse,
metal/normalfacilities for amplification of low level
signal in applicationsrequiring very low noise per-
formances.
Each channel consists of two cascaded opera-
tional amplifiers.
The first one, AMP1, has a fixed gain of 36dB,
low noise forward/reverse switchable input, and
allows magnetic heads connection directly to
ground. The secondone, AMP2, is a standardop-
erational amplifier whose equalizing external
componentsfix the frequencyresponse.
The Audio Music Sensor circuit detects the inter-
program space and then the starting point of mu-
sical programs (the interprogram time and pro-
gram detectiontime are externallyselectable).
The device contains Dolby B decoder NR chains
requiring very few external components and do
not requirecoils.
