I2C-bus controlled 4
45 W best efficiency amplifier
To enable short start-up times, the 70 k
input resistor is reduced to 3 k during start-up
until just before the start-up mute release.
The speaker fault detection (double-fault condition, one side of the speaker connected to
ground and one side connected to one output) is detected during start-up, just before
mute release.
If the amplifier is switched off by I2C-bus (IB1[D0] = 0) the soft mute is activated and the
capacitor on pin SVR is discharged. If the amplifier is switched off in legacy mode,
pin STB must be set to mute for 50 ms to ensure a low switch-off plop and then pin STB
can be set to ground which discharges the SVR capacitor.
If the amplifier is switched off by pulling pin STB LOW, the amplifier is muted (fast mute)
and then the capacitor on pin SVR is discharged. This fast mute can be used in I2C-bus
and legacy mode, when for instance an external engine start detection is used.
