DIGITAL CONTROLLED STEREO
AUDIO PROCESSOR WITH LOUDNESS
DESCRIPTION
The SC7313 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 BIPOLAR/CMOS technology, low
distortion, low noise and low DC stepping are obtained.
