PAM8403

XST-MZ-104 PAM8403 miniature digital power amplifier board

XST-MZ-104
XST-MZ-104 miniature digital power amplifier board uses PAM8403 low-voltage stereo digital power amplifier IC. Its operating voltage range is 2.5~5.5V. It can be powered by 18650 lithium battery or 5V mobile phone charger, and the efficiency is not less than 90%. When the power supply voltage is 5V and the speaker is 4Ω, the output power can reach 2x3W. Can be widely used in portable audio devices such as Bluetooth speakers, MP3 players and headphones.

  • Model Number:XST-MZ-104
  • Type:Amplifier IC Development Boards and Kits
  • Place of Origin:Guangdong, China
  • Brand Name:Xunster
  • Chipset:PAM8403
  • Working voltage:2.5-5.5V
  • Horn matching:4-8 Ω
  • Horn power:2-8 Ω
  • Plate size:21 * 19mm

 

 

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

 

 

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

 

 

3. You can use 5V power supply from USB port of computer, or 5V power supply from USB port of mobile phone charger, or use lithium battery power supply

 

 

4. With 90% high efficiency, 3W (left channel)+3W (right channel) output power can be provided under 4 ohm load and 5V power supply. The efficiency of Class A, Class B and other power amplifiers is only about 30%, and Class D power amplifiers are highly respected under the current green trend.

 

 

5. Class D power amplifier has extremely high efficiency, which will not affect the sound quality due to temperature rise, and it does not need to add heat sink, so the occupied volume is very small

 

 

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

 

 

7. Plate size: 21 * 19mm
