DESCRIPTIONThe TDA7309 is a control processor with inde-
pendent 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 micro-
processor interface.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and Low DC stepping
are obtained.
