TDA7388 Circuit – 4 channel amplifier circuit diagram

4 x 45 quad bridge car audio amplifier

The Tda7388 is a Class AB power audio amplifier ic. The packaging in the flex watt 25 and it has to be designed for the High end car stereo amplifier application. It consist of fully complementary PNP and NPN configuration. It also allows the rail to rail output voltage swing, so you don’t want to apply the bootstraps capacitors.

The amplifier ic circuit consist of inbuilt 4 channel audio amplifiers. The IC having high output power capability. The power watts at RMS per each channel of the amplifier delivers 45 w at maximum of 4 ohms.

The optimum configuration of the circuit is 4 x 26w / 4 Ohm @ 14.4 v , 1kHz. The audio amplifier circuit having more features.

Features

• Low distortion
• Providing low output noise.
• Having the standby function.
• Having the feature of Auto mute at minimum supply voltage detection.

Protection

• Great output protection in short circuit to the ground and voltage supply across the load you are connected.
• It having very inductive load.
• Providing Overrating chip temperature, with soft thermal limiter.
