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.
FEATURES
* Input multiplexer:
--3 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 I2CBus
