Stereo audio frequency amplifier on a chip TDA2004 is designed for use in portable and automotive fidelity, is protected against short circuit at the output, overheating, excess voltage. The power amplifier IC chips designed specifically for car radio application, are the high current capability (3.5A) and the capability to drive a very low impedance (down to 1.6R).
The TDA2004 has low noise, low distortion, and robust. The robustness is supported by its operation safety protection features: very inductive loads, load dump voltage surge, overheating, output AC-ground short, fortuitous open ground. Other important things is space and cost saving : very low external components counts, and very simple mounting system with no need for electrical isolation between the package and the heat sink because the heat contact metal of the package is already connected to ground.
The maximum operating DC voltage on the TDA2004A is 18 V. However the device can withstand a DC voltage up to 28V withno damage. Thiscouldoccur during winter if two batteries are series connectedto crank the engine.
