40W/8ohms Audio Amplifier


Posted on Apr 1, 2013

Using the TB2922HQ audio power IC can be designed a very simple and high efficiency power audio amplifier electronic project . TB2922HQ is 2ch BTL audio amplifier for TV or home audio applications. It includes and the pure complementary P-ch and N-ch DMOS output stage. This TB2922HQ power audio amplifier project is very simple to be implemented and require few external electronic parts . The TB2922HQ power audio amplifier module can be used with 4 or 8 ohms load . Using a 4 ohms load this power audio circuit will provide a output power around 40 watts and using a 8 ohms load the circuit will provide a output power of 23 volts . If you’ll use a bridge mode connection this circuit will provide an output power around 70 watts .
