Features, Applications

TWO STEREO AND ONE MONO INPUTS CONTROLLED MUTE FUNCTION (SOFTWARE AND HARDWARE) VOLUME CONTROL IN 1dB STEP FOUR SPEAKER ATTENUATORS: Independent attenuation control Independent mute function ALL FUNCTIONS PROGRAMMABLE VIA I2CBUS DESCRIPTION The is a volume, tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems. Control is accomplished by serial bus microprocessor interface. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. BLOCK DIAGRAM
