Description

The TDA7334 is a monolithic BICmos IC designed for use in stereo cassette player systems. The dual preamplifier contains mute, autoreverse, metal / normal facilities for amplification of low level signal in applications requiring very low noise performance. Each channel consists of two cascaded operational 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 second one, AMP2, is a standard operational amplifier whose equalizing external components fix the frequency response.
