20 Watt Power Amplifier


Posted on Feb 6, 2014

20 Watt Car Power Amplifier circuit diagram bases TDA 2005. This TDA 2005 IC was designed specifically in car audio system for power boosting applications. This IC has a protection against short circuit and overheating. In the above circuit use a bridge configuration that will deliver 20W of output power with 2 ohm speakers. The scheme given here

is a car stereo amplifier circuit can be used in That car or other vehicle. The circuit is based TDA1553, which is a Class-B audio amplifier. As you can see this circuit is very simple, consisting only of theICand thecapacitor6. Here is a circuit diagram of car stereo. This 20w car audio amplifier circuit described here offers a 20watt booster that will allow you to realize the power amplifier with which one can increase the power output from the carstereoup to20Wattsmaximum. The inputINis connected to theoutputof thereceiver, Uoutputis connectedto the speakeras shownoncaraudioamplifierscheme. It is veryimportanttoensurethat thespeakerhas no connection tothe chassis(ground)ifnot, the integrated circuitIC1, aTDA2004will.
