Audio Processor 20-Pin SO T/R

The TDA7309 is a control processor with independent left and right volume control for quality audio applications. Selectable external loudness and soft mute functions are provided. Control is accomplished by serial I²C bus microprocessor interface. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and Low DC stepping are obtained.
