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 .

If is used a 4 ohms load this TB2922HQ power audio amplifier project must be powered from a good filtered DC power supply that will provide an output voltage between 9 and 18 volts , and if is used a 8 ohms load , a DC power supply that will provide a n output voltage between 9 and 26 volts will be required .
Some features provided by this audio power amplifier module are : built-in standby switch function ,built-in muting function , built-in various protection circuits: thermal shut down, overvoltage, out to GND, out to VCC, out to out short speaker burned .
