SC7315
2-CH OUTPUT STEREO AUDIO PROCESSOR
DESCRIPTION
The SC7315 is a volume, tone (bass and treble), balance (left/ right)
and fader 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.
DIP-20-300-2.54
FEATURES
SOP-20-375-1.27
* 2 stereo inputs
* Two speaker attenuators:
--2 independent speakers control in 1.25dB steps for balance and fader
facilities
--Independent mute function
* All functions programmable via serial I2C Bus
* Loudness function
