Description of the audioprocessor
TDA7417
AutoZero-Remain
In some cases, for example if the P is executing a refresh cycle of the IIC-Bus-
programming, it is not useful to start a new AutoZero-action because no new source is
selected and an undesired mute would appear at the outputs. For such applications, it can
be switched in the AutoZero-Remain-Mode (Bit 6 of the subaddress-byte). If this bit is set
to high, the AutoZero will not be invoked and the old adjustment-value remains.
4.3
Loudness
There are four parameters programmable in the loudness stage:
4.3.1
Attenuation
Figure 4 shows the attenuation as a function of frequency at fP = 400Hz.
Figure 4.
Loudness Attenuation @ fP = 400Hz
4.3.2
Peak Frequency
Figure 5 shows the four possible peak-frequencies at 400, 800 and 2400Hz.
