SC7312
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.
