Excellent noise suppression. When there is no input audio, you can't hear any noise even if you put your ear close to the speaker. Two-channel stereo, 5V power supply can output 3W+3W power, can directly drive 4Ω, 8Ω small speakers, large output power, sufficient energy, good sound quality. The unique D-class digital power board without LC filtering can be directly powered by the computer's USB. Double-panel wiring properly solves the ground potential balance and crosstalk between channels caused by wiring. The ultra-miniature design can be easily placed in the small internal space of various digital products, and the amplification efficiency is super high. All the whole board is welded by machine, and the welding quality is not comparable to manual soldering!
Product introduction: PAM8403 mini class D digital power amplifier board
1. Working voltage: 2.5V-5.5V. Note: The power supply voltage should not exceed 5.5V, and the positive and negative power supply should not be connected in reverse.
2. Speaker matching: 4-8 ohms, recommended: 4 ohms; speaker power: 2-8W.
3. It can be powered by a 5V power supply from the USB port of a computer, or a 5V power supply from the USB port of a mobile phone charger, or a lithium battery.
4. High efficiency 90%, under 4Ω load and 5V power supply conditions, it can provide 3W (left channel) + 3W (right channel) output power. The efficiency of class A, class B and other amplifiers is only about 30%, and class D amplifiers are highly respected in today's green trend.
5. Class D amplifiers are extremely efficient, and the sound quality will not be affected by temperature rise, and no heat sink is required, and the volume is very small.
6. The amplifier board has a built-in noise reduction circuit, and there is no crackling noise when the power is turned on/off; the module has short-circuit overcurrent protection and over-temperature protection.
7. Board size: Ultra-micro volume: 1.85*2.11cm
Precautions for use:
Turn on the speaker first and then turn on the power, otherwise it is easy to damage the chip;
because the digital volume control in the module has a large gain, do not let the audio signal input too large to cause the signal to be cut and limited.
Warm Tips: Dear Customers: Our modules are provided for electronic players with certain electronic knowledge! And please read the instructions or product introduction in the product description carefully when purchasing products. If you do not understand the product problems caused by the use, our company will not accept them. Please be cautious when buying.
