1. Saturated square wave output.
2. Voltage ramp on Mute pin:
from 350 mV to 3.05 V in 40 ms.
In case of I2C interface enabled command IB1(D2)=1 (Mute->Unmute) must be transmitted before to start the voltage ramp
on Mute pin.
3. Voltage ramp on Mute pin:
from 2.8 V to 1.2 Vin 40 ms.
In case of I2C interface enabled the I2C command IB1(D2)=0 (Unmute->Mute) must be NOT transmitted before to start the
voltage ramp on Mute pin.
4. ST-BY pin high enables the I2C bus; ST-BY pin low enables ST-BY condition: detailed pin levels description is contained in
paragraph 'I2C habilitation settings' .
