4db/tétel MAX4466 modullapok Electret mikrofonerősítő modul, állítható erősítésű kék kitörési tábla Arduino-hoz
4pcs/lot MAX4466 Module Boards Electret Microphone Amplifier Module Adjustable Gain Blue Breakout Board For Arduino
Features
Power supply rejection ratio: 112dB
Common mode rejection ratio: 126dB
AVOL: 125dB (RL = 100kΩ) rail-to-rail output
Static supply current: andlt;24μA
Gain bandwidth: 600kHz
Power supply voltage: 2.4V to 5.5V (can be directly connected to STM / ARDUNIO / Raspberry Pi and other development board)
Using introduction:
Connect GND to ground, VCC to 2.4-5VDC.
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 using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device.
If you’re connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
