Description of functionality
TDA7404
4.4.3
Low and high frequency boost
Figure 7 shows the different Loudness-shapes in low & high frequency boost.
Figure 7.
Loudness attenuation, fC = 2.4 kHz

Soft-mute
The digitally controlled soft-mute stage allows muting/demuting the signal with a I2C bus
programmable slope. The mute process can either be activated by the Mute pin or by the
I2C bus. This slope is realized in a special S-shaped curve to mute slow in the critical
regions (seeFigure 6).
For timing purposes the Bit 0 of the I2C bus output register is set to 1 from the start of
muting until the end of de-muting.
Figure 8.
Soft-mute timing

Please notice that a started Mute-action is always terminated and could not be interrupted by a change of
the mute -signal.
