Description:
PAM8403 small digital amplifier chip, high-definition sound to highlight the advantages of digital chips, circuit surrounding the most reasonable configuration, power supply filtering is upgraded to 470uf (some sellers do not even have to 100uf not capacitive) 1.6mm glass plate, the real amplifier board did most detailed output 3W + 3W high-fidelity sound, the amplifier is a rare good product enthusiasts, the potential use of original anti-meter body, life expectancy up to 15 years, with switch potentiometer can be directly counter-clockwise off the power, listing has been well received by buyers praise!
Feature:
Model:PA8403
Power:Low Power
Super size:29.5 * 20.2 * 15mm (excluding protruding potentiometer lever)
Excellent noise suppression, in the absence of circumstances connected to input audio ear close to the speaker can not hear any noise, two-channel stereo, 5V power supply can output 3W 3W power, can directly drive 4Ω, 8Ω small speakers, the output power large, full of energy, good sound quality. The unique non-LC filter Class-D digital power board can be directly used computer USB power supply. Double panel wiring, wiring properly resolve the ground potential caused by balance and inter-channel crosstalk, ultra-miniature design, can easily be placed in a variety of digital products within a small space, high amplification efficiency. All using the whole plate welding machine, welding quality comparable non-manual soldering iron!
