TDA7339

Overview
® TDA7339 3 BAND DIGITAL CONTROLLED AUDIO PROCESSOR PRODUCT PREVIEW THREE STEREO INPUT ONE RECORD OUTPUT ONE STEREO OUTPUT TWO INDEPENDENT VOLUME CONTROL IN 1.
0dB STEPS TREBLE, MIDDLE AND BASS CONTROL IN 1.
0dB STEPS ALL FUNCTIONS PROGRAMMABLE VIA SERIAL I2 CBUS DESCRIPTION The TDA7339 is a volume and tone (bass , middle and treble) processor for quality audio application in car radio and Hi-Fi system.
Control is accomplished by serial I2C bus microprocessor interface.
The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.
BLOCK DIAGRAM DIP28 ORDERING NUMBER: TDA7339 Thanks to the used BIPOLAR/MOS Technology, Low Distortion, Low Noise and Low DC stepping are obtained.
