This is a design circuit for amplifier that is produces amp 20 Watts. This circuit is based on op amp TDA2004. The circuit can use in a car. This is the figure of the circuit.
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, the output AC-ground is 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.
