The MP34DT01-M has an acoustic overload point of 120dB. Its SNR Is 61dB and sensitivity is -26dB. The total harmonic distortion and noise figure is less than 1% at a sound pressure level of 100dB.
The MP34DT01-M consists of a capacitive sensing element, manufactured using a special silicon micromachining process dedicated to audio sensors, and an interface IC.
This IC is a CMOS device which provides a digital signal in pulse-density modulation format.
The MP34DT01-M is available in a top- port, surface-mount, EMI-shielded package which measures 3mm x 4mm x 1mm. It is guaranteed to operate over an extended temperature range from -40°C to 85°C.
