1.4W Stereo Power Amplifier Circuit based TDA8552

Stereo Amplifier TDA8552A few more words on the chip. This is a bridge amplifier class AB integrated into the protection against overheating, short circuit protected outputs, suppression of inrush current when you turn on and off the amplifier. The only difference – a little more power output – 1.4 watts per channel. But nevertheless, it also does not require a heat sink and can be used anywhere.

On this chip there is a difference in the headphone sense pin pin number 4. This will detect when a headphone jack inserted into the connector. For more information see the datasheet here.
