Stereo Amplifier Board, DROK Micro Digital Amp Module High

Stereo Amplifier Board, DROK Micro Digital Amp Module High Power Dual-Channel Two CH Class-D Audio Amplifier Chip Support 5V USB Power Supply
- Power Supply: DROK stereo amplifier board power supply is DC 3. 6-5. 5V. It can be powered by single-cell lithium battery or USB. It can also be powered by four 1. 2V batteries.
- Output power: 3W+3W (4 ohms); SNR: 90dB; Efficiency: >90%; Maximum closed-loop gain: 24DB
- Easy to install: Ultra-thin board, easy to install in everywhere you want.
- User-friendly design: The amplifier is featured by special output processed circuit, has a lower EMI value than traditional LC. Moreover, it has built-in standby electronic switch, high gain buffer amplifier and short circuit protection.
- Notice: This amplifier module does NOT have reverse connection protection and the supply voltage cannot exceed 5. 5V, or the amplifier will be burned.
Specifications:
Efficient digital amplifier chip, Built-in standby electronic switch, built-in high-gain buffer amplifier, built-in short circuit protection.
Input: DC 3.6v-5.5V (the chip will burn out if more than 5.5V.)
Output power: 3W +3 W (4 ohms)
Signal to Noise Ratio: 90dB
Efficiency:> 90%
Maximum closed-loop gain:24DB

Notice:
positive and negative power supply can not be reversed, the supply voltage can not exceed 5.5V, or it would burn out the IC.
On-chip high-gain buffer, can not change any component. Improper parameters would lead to IC damage.
Please try to use the input line with shield wire, to removing clutter and current sound.
CMOS BTL Driver Output, Left and right negative of speakers can not be connected together, 4 speaker wire is completely independent, Not allow connect together.

if use with computer, powered by the computer USB, that would caused current sound. because the audio and USB common ground, so the current sound is unavoidable.
