描述 Description

The U7313 is a 3-stereo inputs and 4-speaker outputs digital audio processor which incorporates volume, tone(bass and treble) , balance(left/right)and fader(front/rear) into a single chip. Selectable input gain and loudness function are provided to build a highly effective electronic audio processor having the highest performance and reliability with the external components. The AC signal setting is obtained by resistor networks and switches which are set by programming serial input signal via I 2 C bus. In addition, BiCOMS processes are utilized for low distortion, low noise and low DC stepping. The U7313 is designed for quality audio applications in car radio and Hi-Fi systems.
