Overview
® TDA7335 STEREO PREAMP + AMS + DOLBY B* NOISE REDUCTION PROCESSOR DUAL CHANNEL PROCESSOR FOR PLAYBACK APPLICATIONS.
STEREO DOLBY B NR SYSTEM LOW NOISE HEAD PREAMPLIFIER MUTE, AUTOREVERSE, AMS (AUDIO MUSIC SENSOR) FUNCTIONS INTERNAL SWITCHES FOR EQUALIZATION DOLBY REFERENCE LEVEL -6dBm (388.
2mVRMS) MINIMUM NUMBER OF EXTERNAL COMPONENTS LOW SUPPLY CURRENT (18mA) MIXED BIPOLAR/CMOS TECHNOLOGY 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.
The first one, AMP1, has a fixed gain of 36dB, low noise forward/reverse switchable input, and allows magnetic heads connection direct...
