Description
A small module with a MEMS microphone ADMP401. Characterized by 67 times gain, works with a voltage from 1.5 V to 3.3 V. The output is an analog signal.
The device has a gain of 67 times. The output voltage of the AUD fluctuates at half the supply voltage Vcc, when the microphone detects sound. The amplifier provides volatge Vpp 200 mV at arm's length and on a normal conversation volume level, so that the output AUD can be linked directly with the matrix A/C of any microcontroller.
