DESCRIPTION

   The    SC7314  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.
