PAM8403 Super mini digital power amplifier board
Small power amplifier board
High power 3W dual channel
Power supply: DC 1A (DC): 5V
Output power: 3W+3W (4 Euro)
Signal to noise ratio: 90dB
Efficiency: more than the 90%
Size: 24 x 15.5 x mm
location hole size: pitch 20mm, aperture: 2mm
Matters needing attention:
Power positive and negative can not be reversed, the power supply voltage can not exceed 5.5V, these two violations will cause IC damage.
On-chip high gain buffer, can not change any component parameters on board, the parameters do not meet will lead to IC damage.
Input line, please use the shielded line as far as possible, can play an anti-interference role, eliminate the noise of the current of the wave.
The output is CMOS tube BTL drive mode, the negative electrode of the left and right speakers can not be connected together, that is, the 4 lines of the speaker are completely independent, and no joint connection is allowed!
Material:Metal
Colour:Red
Quantity: 1 pcs
