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. More: 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.

The TB2922HQ audio power amplifier IC is designed for high efficiency in audio applications, specifically targeting two-channel BTL (Bridge Tied Load) configurations suitable for television and home audio setups. The integrated circuit features a pure complementary P-channel and N-channel DMOS output stage, which enhances performance and efficiency by reducing distortion and improving power handling.

This amplifier circuit is straightforward to implement, requiring minimal external components, which simplifies the design process. The circuit can accommodate speaker loads of either 4 ohms or 8 ohms. When operating with a 4-ohm load, the amplifier is capable of delivering approximately 40 watts of output power. In contrast, with an 8-ohm load, the output power is around 23 watts. For configurations utilizing bridge mode, the output power can reach up to 70 watts, making it suitable for driving larger speakers or more demanding audio applications.

To ensure optimal performance, the power amplifier must be supplied by a well-regulated DC power supply. For a 4-ohm load, the supply voltage should be between 9 and 18 volts. When using an 8-ohm load, the required DC supply voltage increases to a range of 9 to 26 volts. This flexibility in power supply requirements allows for greater versatility in various audio setups.

The TB2922HQ module includes several built-in features that enhance its usability and reliability. These features include a standby switch function, allowing for energy savings when the amplifier is not in use, and a muting function to eliminate unwanted noise during transitions. Additionally, the amplifier is equipped with various protection circuits, including thermal shutdown to prevent overheating, overvoltage protection, and safeguards against short circuits between outputs and ground or VCC. These protective measures help ensure the longevity and reliability of the amplifier in demanding audio environments.Using the TB2922HQ audio power IC can be designed a very simple and high efficiency power audio amplifier electronic project .
