4-CH OUTPUT STEREO AUDIO PROCESSOR WITH 4 STEREO INPUTS AND TONE/VOLUME CONTROL
DESCRIPTION
The SC7312 is a volume, tone (bass and treble), balance (left/ right) and fader(front/rear) processor for quality audio applications in car radio and Hi-Fi systems. Selectable input gain and external loudness function are provided. Control is accomplished by serial I2C bus microprocessor interface. The AC signal settings is obtained by resistor networks and switches combined with operational amplifiers. Due to the Used CMOS technology, low distortion, low noise and low DC stepping are obtained.
SOP-32-375-1.27
FEATURES
* Input multiplexer: --4 stereo inputs --Selectable input gain for optimal adaptation to different sources * Four speaker attenuators: --4 independent speakers control in 1.25dB steps for balance and fader facilities --Independent mute function * All functions programmable via serial I 2C Bus * Loudness function * Volume control in 1.25dB steps * Treble and bass control * Input and output for external equalizer or noise reduction system
