DESCRIPTION
The TDA7334 is a monolithic BICmos IC de-
signed for use in stereo cassetteplayer systems.
The dual preamplifier contains mute, autoreverse,
metal/normalfacilities for amplification of low level
signal in applicationsrequiring very low noise per-
formance.
Each channel consists of two cascaded opera-
tional amplifiers.
The first one, AMP1, has a fixed gain of 32dB,
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.
