STMicroelectronicsTDA7388Amplificador de audio

The STMicroelectronics Audio Amplifier has a wide range of sound with 4 speaker channel (Quad) stereo 26W Class -AB Automotive 25-Pin (25+Tab) FLEXIWATT (Vertical) Tube amplifier. It has Overrating chip temperature with soft thermal limiter and it protects the Output short circuit to ground, to VS, across the load. The product is fully based on complementary PNP/NPN configuration, it allows a rail to rail output voltage swing with no need for bootstrap capacitors. The extremely reduced boundary components count allows very compact sets. Its maximum power dissipation is 80000 mW. This audio amplifier can handle a current up to 5500 mA. It has a maximum load resistance of 4 Ohm. This audio amplifier has a maximum operating temperature of 150 °C.
