DESCRIPTION

 PAM8403 Digital Small Power Audio Amplifier Board Support USB Power Supply 5V

PROJECT  DESCRIPTION:

        PAM8403 mini 5V power amplifier board Support USB Power supply 
This power Amplifier board adopts original PAM Digital power amplifier chip IC,simple design but steadily function,suitable for battery or portable electronics products, suitable for long time steady usage.
Board adopted original Long Ding PAM8403 digital power amplifier chip (mostly home-made chips on the market), circuit is simple, reliable work. Working voltage of 2.5 V to 2.5 V, 3 wx2 maximum output, efficiency can achieve 90% above, can use computer USB 5 V power supply, is very suitable for battery and portable electronic products. Bat small size, and is equipped with switch, potentiometer, can follow one's inclinations of the volume, and control the power switch to use and install is very flexible and convenient. Using devices all use the real thing, can be competent for long-term stability.

Boards are finished plate welding test, the above potentiometer is with switch, can control the volume and power switch, not more than 5.5 V, working voltage power supply positive and negative don't wrong, otherwise the chip has the potential to damage.

Excellent noise suppression in the case is not connected to the input audio, the ear close to the speaker cannot hearing any noise 
Unique without LC filter Class D digital power board, and can be used directly to the computer's USB powered. 
Dual-panel wiring, properly solve the crosstalk between the ground potential balance and channel wiring 
Ultra-miniature design, can easily be placed in the internal space for a variety of digital products, ultra-high zoom efficiency. 
All using the machine for the entire board soldering, hand soldering iron welding quality comparable! 
Noise canceling circuit was built in the amplifier board

Feature:

Operating voltage: 2.5V-5.5V

  • Maximum output power: 3W*2(5V 4Ω)
  • Size:apporx.30*22*16mm
  • Built with switch Potentiometer, can adjust the volume & control power switch freely!
  • Flexible assembly usage.
  • 3W Output at 10% THD with a 4 Load and 5V Power Supply Filterless
  •  Low Quiescent Current and Low EMI Low THD+N Superior Low Noise Efficiency up to 90% Short Circuit Protection Thermal Shutdown Few External Components to Save the Space and Cost

Note: The left and right channel output of the "negative" cannot, and then together, otherwise it will burn the IC and energized speaker (load) connected before.
