Tape & Reel

SERIAL I²C BUS

The AC signal setting is obtained by resistor net-

works and switches combined with operational

amplifiers.

2 DESCRIPTION

The TDA7309 is a control processor with indepen-

dent left and right volume control for quality audio

applications. Selectable external loudness and

soft mute functions are provided.

Thanks to the used BIPOLAR/CMOS Technology,

Low Distortion, Low Noise and Low DC stepping

are obtained.

Control is accomplished by serial I²C bus micro-

processor interface.
