Clip Detection
The output clip detection terminal, pin 4, has an open collector output structure on chip as shown in
Figure 3. In the case when the output waveform is clipping, the clip detection circuit is operated and the
NPN Tr. is turned on.
It is possible to improve the audio output quality by controlling the volume and/or tone control circuits
through a low pass filter (L.P.F) smoothing circuit as shown in Figure 3.
The sensitivity of the circuit to clipping level can be selected T.H.D.
= 1% or 10% via I2C bus.
In the event that this function is not used, pin4 should be left open circuit.
