20 watt Car Power Amplifier using TDA2004

This circuit diagram we Power Amplifier IC TDA2004. Main features of this powerful package MULTIWATT ® (a trademark of SGS-THOMSON Microelectronics), where an IC chip power amplifier is designed specifically for car radio applications, is the ability of high current (3.5A) and the ability to drive a very low Impedance (down to 1.6R). TDA2004 low noise, low distortion, and strong. Sense of security operations supported by the protection features: highly inductive load, the load dump voltage surge, too hot, AC-ground output short, fortuitous open ground. Here is a schematic diagram of a standard circuit:

This is another important cost and storage space: a very low external component count, and very simple mounting system with no need for electrical isolation between the package and heat sink because the heat from the metal contacts of the package are connected to land.
