Elektrēta kondensatora mikrofons ar pastriprinātāju MAX4466, regulējams pastiprinājums
Barošana: 2.4 – 5 VDC, ieteicams 3.3V.
Ar iebūvētu trimeri var regulēt pastiprinājumu (gain) no 25x līdz 125x.

Electret Microphone Amplifier MAX4466 With Adjustable Gain
Power supply 2.4 – 5 VDC, 3.3V recomended.
Small trimmer pot to adjust 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, the output can go up to 5Vpp!
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).
