Ultra small High-power Amplifier Board .Voltage Range DC 3.6v-5.5V. It has High-power Output,Energy-saving,Short-circuit protection ect
Feature:-
Power Supply: DC 3.6v-5.5V,
Single lithium battery, USB powered, or four 1.2V batteries, Transformer power supply must be 5V voltage regulator, the chip will burn out if more than 5.5V - Output power: 3W +3 W
- SNR: 90dB
- Efficiency: >90%
- Size：24x15.5mm
- Hole Size: Pitch 20mm, Bore: 2mm
- Positive and negative power supply can not be reversed, Supply voltage must not exceed 5.5V, otherwise the IC will burn out.
- build-in high-gain buffer, please do not change any component of the board, otherwise will lead to IC damage.
- Please try to use the input line with shielded cable, Eliminate clutter current sound.
- CMOS BTL output, 4 speaker wire connection is completely independent, please do not connect together.
