1.LM3886TF, the biggest advantage of the chip is that it has the output anti-impact measures, so there is no need to use the horn relay delay, which is most suitable for subwoofer, because the strong vibration of the subwoofer is easy to make the relay contact jump.
2.TDA7294, also has the power on silence delay function, the final stage uses the field effect power tube output, so the chip has the taste of the machine.
3. Use the common commercially available \"fool block\" 1100. The circuit is simple, without a circuit board, the connection is also a field effect tube output, the effect is quite good
The ANT8108 is an ultra-low EMI, high signal-to-noise ratio, crack-proof, 5W single-channel Class D audio amplifier. Under the condition of 5V power supply, driving 2Ω load can output 5W power. ANT8108 uses a low noise active device process to ensure a high signal-to-noise ratio of amplifier output. ANT8108 built-in overheat protection function to ensure the reliability and stability of the chip in various application environments.
