FEATURES
2 STEREO INPUT 1 STEREO OUTPUT TREBLE BOOST BASS CONTROL BASS AUTOMATIC LEVEL CONTROL VOLUME CONTROL IN 1dB STEPS MUTE STAND-BY FUNCTION SOFTWARE CONTROLLED ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS Figure 1. Package SSO20P Table 1. Order Codes Part Number TDA7463AD Package SSO20P The control of all the functions is accomplished by serial bus. 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 DC stepping are obtained. 2 DESCRIPTION
