Output Clip Detection Function
Figure 6. In case that the output waveform is clipping, the clip detection circuit is operated and NPN Tr. is
turned on.
smoothing circuit as shown in Figure 7.
The output clip detection terminal of pin 25 has the open collector output structure on chip as shown in
It is possible to improve the audio quality with controlling the volume, tone control circuit through L.P.F.
In case of being unused this function, use this IC as open connection on pin 25.
