1.4.3 Low & High Frequency Boost
Figure 5 shows the different Loudness-shapes in low & high frequency boost.
Figure 5. Loudness Attenuation , fC = 2.4KHz
1.5 SoftMute
The digitally controlled SoftMute 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 (see Figure 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 6. Softmute-Timing
Note: Please notice that a started Mute-action is always terminated and could not be interrupted by a change of the mute -signal.
