are reset, the amplifier is switched off and the DIAG pin is pulled LOW to indicate that a
power-on reset has occurred (see bit DB2[D7]). When bit IB1[D0] is set, the power-on flag
is reset, the DIAG pin will be released and the amplifier will start-up.
In legacy mode a supply voltage drop below 5 V will switch off the amplifier and the DIAG
pin will not be pulled LOW.
The DC output voltage of the amplifier (V
related to the voltage on the SVR pin (see
connected on the SVR pin to suppress the ripple on the power supply.
If the supply voltage drops, for instance, during an engine start, the output follows slowly
due to the SVR capacitor. The headroom voltage is the voltage needed for good operation
of the amplifier and is defined as V
becomes lower than the headroom protection threshold of 1.6 V, the headroom protection
is activated to prevent pop noise at the output. This protection first activates the hard mute
and then discharges the capacitors on the SVR and ACGND pins to generate more
headroom for the amplifier (see
