TA8210AH - 2 x 22W BTL Car Amplifier Circuit

 

This is a circuit of 2 x 22 watt BTL amplifier using IC TA8210AH. It is not only an auto amplifier, ideal for a low-frequency auditory approach those hi-fi, with a very good linear feature. Can be fueled by a 12 volt car battery but shi from a 12 volt charger. The chip incorporates four bridge amplifiers available in two by two in order to ensure the output 22 watts per channel on 4 ohms.

TA8210AH - 2 x 22W BTL Car Power Amplifier Circuit

Note:

• IC TA8210AH must be connected to a heat sink. A computer cabinet fan can also be used in addition.
• The circuit roughly draws 6A current at 18 V at full volume.So the power supply must be any thing more than 6A.
