Features
:
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.
