High-Power 2-Channel 3W Audio Super Mini Digital Amplifier Board for Electronics Development & Projects (Red)..!

Product Information

Key Features

Super mini digital amplifier board, ultra-thin, can be very convenient to place in the gap of small plastic boxes
or other devices. It can obtain maximum power output at a lower voltage. Built-in standby electronic switch,
high-gain buffer amplifier, short circuit protection. It is perfect for MP3/MP4

Description

New efficient digital amplifier chip
Special internal output processing circuit
Eliminating the conventional LC network
Using EMI
Power supply: (DC) 3.6v-5.5V
Output power: 3W +3 W
Signal-to-noise ratio: 90dB
Efficiency: >90%
2 channels 3W amplifier with PAM8403
Output is CMOS BTL driver
Cannot change any component parameters to protect IC
The board can also powered by 5V USB power supply or 4 x 1.5V batteries
It is perfect for MP3/MP4

Product Notes:

Power positive and negative can not be reversed, the supply voltage can not exceed 5.5V, these two
violations can lead to IC damage. On-chip high-gain buffer can not be altered to to board any component
parameters; will result in IC damage. Input line try to use shielded line for an anti-jamming effect, eliminate
clutter current sound. Output for CMOS tube BTL driver, the negative terminal of the left and right speakers
can not be together, that the four lines connecting to the speaker is completely independent, and does not
allow total access.
