Product data sheet
When the SVR capacitor has discharged, the amplifier starts up again if the V
above the low V
outputs of the amplifier remain low. In I
typically 5 V, results in setting bit DB2[D7] and not starting of the amplifiers but waiting for
an I
The amplifier prevents audio pops during engine start. To prevent pops on the output
caused by the application during an engine start (for instance tuner regulator out of
regulation), the STB pin can be made zero when an engine start is detected. The STB pin
activates the fast mute and disturbances at the amplifier inputs are suppressed.
