5. Muting function: Pin(1), pin(25)
By means of controlling pin(25) (mute control terminal) less than about 1.5V, it can make the IC muting
condition as below. However, pin(25) must not be connected to a certain voltage, for example, VCC, VDD, Vref, …
etc. In other words, pin(25) is inhibited to be pulled up, for instance fig. 5 application.
The attenuation by the muting function is 70dB (typ.). This muting is very smooth attenuating by the time
constant of pin(1): smoothing.
Therefore, this function is suitable to the audio muting. The time for attenuation: Tatt is adjustable by changing
the capacitance of C3. But the tatt may influence the popping noise level.
So, please decide the time of tatt by testing on the units.
6. AUX. amplifier: Pin(16)
The pin(16) is for input terminal of AUX. amplifier.
The total gain is 0dB by using of AUX. amplifier.
Therefore, the -con can directly drive the AUX. amplifier.
