A ready-made audio frequency amplifier board with a volume control and a radiator.
This amplifier is built on the TDA7297 microcircuit, which has a wide range of supply voltage 6.5 ... 18V, which allows it to be used in a car instead of a standard amplifier ... It can also be used in any other low-voltage device: active speakers, music centers, radio and other multimedia devices.
It has convenient terminals for connecting speakers and power and a 3.5 jack for the input signal. It can also operate from a weak signal source, which indicates a good sensitivity of the amplifier, has a deep high-quality bass.
What is important, the microcircuit has protection against short circuits and protection against overtemperature on it.
Power supply can be either constant or alternating voltage. There is a rectifier diode on the board, which also serves as protection against voltage reversal.
