SC7313
4-CH OUTPUT STEREO AUDIO PROCESSOR WITH 3 STEREO INPUTS AND
TONE/VOLUME CONTROL
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 CMOS
technology, low distortion, low noise and low DC stepping are obtained.
FEATURES
* Input multiplexer:
--3 stereo inputs
--Selectable input gain
* Four speaker attenuators:
--4 independent speakers control in 1.25dB steps for balance and
fader facilities
--Independent mute function
* All functions programmable via serial I2C Bus
* Loudness function
* Volume control in 1.25dB steps
* Treble and bass control
* Input and output for external equalizer or noise reduction system
