Description:
PAM8403 is a small digital power amplifier chip. High-definition sound quality highlights the advantages of the digital chip. The circuit adopts the most reasonable peripheral configuration. The power amplifier board is the most meticulous, and the output is 3W + 3W high fidelity. Sound quality, the potentiometer uses the original anti-body, the service life can reach 15 years, the potentiometer with switch can reverse the power supply directly.
This board adds a 1000UF filter capacitor because some buyers are powered by computer USB (experiments have proved that as long as the board uses the PAM8403 chip, if the filter capacitor is less than 470UF when powered by computer USB, there must be hum. In this regard, our shop re-modified the PCB board and added a 1000UF filter capacitor to completely solve the problem of humming when the computer is powered by USB.
The power amplifier board adopts PAM8403 digital power amplifier chip, which is ultra-thin and small in size, suitable for computer USB interface power supply.
