Advantages of class D power amplifier IC
1. Class D power amplifier has a high energy conversion rate, and it is small in size and has strong reliability. The battery utilization rate of class D power amplifier can reach more than 90%, meeting the requirements of green environmental protection.
2. Class D power amplifier has a wide range of applications, and the minimum load impedance connected to it can be very low. In addition, no matter how the load impedance changes, the conversion rate of its battery is basically unchanged
3. Class D power amplifier has no relative changes in high frequency, intermediate frequency and low frequency. Its sound is very clear and the sound image is accurately positioned.
4. Class D power amplifier is very suitable for mass production of products. As long as the correct components are installed, the products can have good consistency, and no debugging is required in the production process, which is safe and reliable.
5. Class D power amplifier can directly realize group control, remote control, monitoring and other functions without adding any device.
Disadvantages of class D power amplifier IC
Although class D power amplifier has many advantages, it also has many disadvantages, and these disadvantages seriously affect the development of class D power amplifier. Next, I will talk about the disadvantages of class D power amplifier.
1. There is no special switch for class D power amplifier. If the installed power transistor and other devices do not match well, the quality of the whole product will be poor.
2. During the initial connection and final closing of the power transistor of class D power amplifier, the potential close to the ground will fluctuate, which increases the noise.
3. The output circuit of class D power amplifier may have a dead zone.
4. The loudspeaker of class D power amplifier may be distorted for some reason.
