Descriptions: PAM8403 Audio Amplifier Module
PAM8403 small power mini 5 V power amplifier board (can be powered by USB) (XY) USA plate PAM8403 digital power amplifier chip, the circuit is simple, reliable work. Operating voltage from 2.5 V to 2.5 V, 3 wx2 maximum output, efficiency can reach 90% or above, can use the computer USB 5 V power supply, is very suitable for battery and portable electronic products. Bat small size, and it is equipped with the switch, potentiometer, can follow its volume inclines, and control the power switch for use and installation is very flexible and convenient. Using all-purpose devices of the real thing may be competent for long-term stability.
operating voltage: 2.5 V to 2.5 V
maximum output: 3 wx2 (5 v 4 o)
plate size: about 22mm 30mm wide / depth/height 16mm excluding potentiometer handle bulge (dimension) boards are finished welding test board, the above potentiometer is with switch, can control the volume and power switch, no more than that 5.5 V, positive and negative power supply voltage does not do wrong, otherwise the chip has the potential for damage.
