TDA7375A 2x35W (2x25W) Dual Channel Stereo Audio Power Amplifier AMP Board

Product Description

TDA7375A is a four-channel surround sound power amplifier chip produced by STMicroelectronics. It is widely used in car audio circuits and also used in multimedia audio equipment.
Single row, dual column, 15 pin package, output power 2x35W (MAX/4Ω); 2x25W/8Ω 14.4V, 1kHz, THD=10%.
It has the following characteristics:
Minimum external components; no external damping capacitor required; internal fixed gain / 26db; btl boot without impact noise; dc-ac short circuit protection; internal overload over temperature protection
Installation and use note:
1. The power supply board is powered by DC 12-15V. It can be powered by switching power supply and battery. The 10A diode on the board is a protection against positive and negative poles. It is not used for rectification.
2. There is no need to install insulation sheets between the chip and the heat sink, but it is best to apply some grease for better heat conduction!
3. When the power is tested, the signal input terminal on the board should be connected to the load and cannot be suspended. Otherwise, there will be induced noise, and the signal line should use the shielded wire as much as possible.
4. If the board is installed in the chassis, be sure to connect the chassis of the chassis to the ground of the input on the board.
