U7313
AUDIO PROCESSOR IC
„ 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 I2C 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.
„ FEATURES
* Support I2C bus interface
* 3 stereo inputs and selectable input gain
* Volume control in 1.25dB/step
* Loudness function
* Bass and treble control
* 4 independent speakers control
* Independent mute function
* Low distortion
* Low noise and DC stepping
