1. Working voltage: 3.8V-12V (voltage falls below 4V sound will be
significantly reduced, the maximum can not exceed 15V).
2. Operating Current: 1mA (static) to 150mA (max).
3. Output Speaker Impedance: 4 ohms -32 Euro (high impedance voice, high
efficiency, if there is no confidence in their own horn, you can buy the shop
sold the speakers, the sound is very loud).
4. Supported Speaker power: 0.5W-25W (in fact, any power speaker can be used,
speaker volume, and power is not so much, as long as the amplifier output is
greater than the rating on the line, big horn sound may be bigger point).
5. Output power: 750mW (max).
6. Volume: 20mm * 12 mm * 7.5mm(LxWxH).
7. used to make very good mic preamp, AC ripple and noise is low, the output
signal voltage is greater than 1V or more, and promote post-amp signal values
are very strong.
8. The output volume can be adjusted range: 0 to 100%, on-board potentiometer
only fine-tuning, the conventional audio volume can be adjusted directly by
control. Package include: 1 x Mini LM386 Audio Power Amplifier Board DC
