PAM8406 Digital Power Amplifier Board - PAM 8406 With Volume Potentiometer
+ Excellent noise suppression, no noise can be heard when the ear is attached to the speaker without inputting the input audio.
+ Two-channel stereo, 5V power supply can output 5W+5W power, can directly drive 4 ohm, 8 ohm small speakers, large output power, energy enough, good sound quality, with left and right channel volume adjustment.
+ The unique LC-free digital amplifier board without LC filtering can be directly powered by the USB of the computer.
+ Double panel wiring, properly solve the ground potential balance caused by wiring and crosstalk between channels
+ Ultra-miniature design, can be easily placed in the small internal space of various digital products, the amplification efficiency is very high.
+ Rated working voltage 2.5-5V, the limit working voltage is 5.5V.
Note: The "negative" of the left and right channel outputs cannot be connected together, otherwise the IC will be burned and the speaker (load) should be connected before power-on.
