Car Stereo Amplifier Circuit

Car Stereo Amplifier Circuit

Given below is the circuit of a car stereo amplifier that can be used in cars or other vehicles. We have used TDA1553, which is a Class-B audio amplifier.

Description :

Here is the circuit of a car stereo amplifier based on TDA1553. TDA1553 is a monolithic Class-B audio amplifier which contains 2 x 22 watt amplifiers in bridge tied load configuration. The amplifier operates from 12V DC and is developed intentionaly for car audio applications. The IC also has a load of good features like short circuit protection, load dump protection, reverse polarity protection, loud speaker protection etc.

In the circuit , C5 and C4 are input decoupling capacitors while C3 sets the delay time for loud speaker protection. C1 and C2 are power supply filter capacitors.

    I want to make an electronic circuit of car stereo amplifier. so i want capacitor of 100nF . and i have here 2 capacitors with me 1000uF and o.1uF . which capacitor will give me same effect as 1oonF ?

    on every capacitors tolerance as 100uF and voltage as 10v are mentioned. but i have noticed in same circuit that they have not mentioned voltage of capacitors. which voltage capacitor should i take in this circuit? kindly help me sir.
