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.
