SLAVE ADDRESS W
SLAVE ADDRESS R
The fader is located at the end of the tone/volume chain. The balance between the front
and rear channel can be controlled by attenuation of either the front or the rear channel.
Control range is 0 dB to 64 dB with a step size of 1 dB. Optionally the fader attenuation
can be activated for front and rear channels together.
The tone control output signal is available on two pins. Furthermore two input pins allow
connection to the fader block for front and rear line outputs, or alternatively for rear output
only. This allows connection of an external sound processing circuit for equalizing,
surround sound or sound stage positioning. Also input or mixing of an external signal
source like navigation voice or beep can be realized.
SDA and SCL HIGH and LOW internal thresholds are specified according to both 2.5 V
and 3.3 V I
maximum I
mode specification.
