Description of the audio processor
TDA7419
4.4.3
Low and high frequency boost
Figure 6 shows the different loudness shapes in low and high frequency boost.
Figure 6.
Loudness attenuation, fC = 2.4 kHz
4.4.4
Flat mode
In flat mode the loudness stage works as a 0 dB to -15 dB attenuator.
4.5
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 soft-mute pin or by
the I2C bus. This slope is realized in a special S-shaped curve to mute slow in the critical
regions (see Figure 7).
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 demuting.
