Hi @MHelk.1 , the output of the analog mic MP23ABS1 is basically ratio-metric. This means that if you supply the device with Vdd = 2.7V (the typical datasheet value), you will get an output offset of almost Vdd/2 (DC level value), with the signal superimposed on it. For example, if the input signal is a sinewave at 1kHz, 120dBSPL, being the sensitivity typ value -38dBV, the output signal will be DC level + sinevave at 1kHz of about 300mV peak. The output frequency is the same one of the acoustical input wave. Regards
