DESCRIPTION

The TDA7335 is a monolithic BICmos IC de-

signed 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 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 second one, AMP2, is a standard op-

erational amplifier whose equalizing external

components fix the frequency response.

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 detection time are externally selectable).

The device contains Dolby B decoder NR chains

requiring very few external components and do

not require coils.
