Product Introduction: PAM8403 mini Class D amplifier board

1. Working voltage: 2.5V-5.5V. Note: The power supply voltage should not exceed 5.5V, and the power supply should not be reversed.

2. Horn matching: 4-8 ohms, recommended: 4 ohms; Speaker power: 2-8W.

3. It can be powered by 5V power supply from the USB port of the computer, or by 5V power supply from the USB port of the mobile phone charger, or by lithium battery power supply.

4. High efficiency 90%, 4Ω load and 5V power supply, can provide 3W (left channel) + 3W (right channel) output power.

5. Class D power amplifier has high efficiency, will not affect the sound quality due to temperature rise, and does not need to add heat sinks, and occupies a small volume.

6. The power amplifier board has a built-in noise cancellation circuit, and there is no crackling noise when the power is turned on/off; The module has short-circuit, over-current protection and over-temperature protection.

7. Board size: 1.85*2.11cm

Apply:

LCD TV, monitor

laptop

Portable speakers

Portable DVD player, game console

Mobile/speakerphone

Precautions for use:

Turn on the speaker first and then turn on the power supply, otherwise it is easy to cause damage to the chip; Since the digital volume control in the module has a large gain, don't let the audio signal input be too large and cause the signal to cut and limit; The "negative" of the output end of the left and right channels cannot be connected together, otherwise the IC will be burned, and the horn (load) should be connected before powering on.
