ماژول تقویت کننده میکروفون MAXIM MAX4466:
Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, the Maxim MAX4466 is used, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn’t nearly as noisy or scratchy as other mic amp breakouts we’ve tried!
This Best Breakout IS SUCH AS Used for the Projects Voice Changers, Audio recording / sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. that’s down to be about 200mVpp (for normal speaking volume about 6 “away) which is good for attaching to something that expects ‘line level’ input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, Output CAN Go up to at The 5Vpp!
the Using IT IS Simple: Connect to the GND Ground, the VCC to the For 2.4-5VDC at The Best Performance, use at The “Quietest” Supply’s the Available (ON AN the Arduino, the this Would BE at The 3.3V Supply’s).. The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC / 2 so when its perfectly quiet, the voltage will be a steady VCC / 2 volts (it is DC coupled). If the audio equipment you ‘Re The requires a using the AC Coupled Audio, Capacitor 100uF the BETWEEN A Place at The Output at The PIN and the INPUT of your Device. Connecting to the If you’re AN Audio Differential Amplifier that has the Inputs or the includes Decoupling Capacitors, at The 100uF CAP IS Not required.
