The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to produce audio sensors. The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format. The MP34DT01 has an acoustic overload point of 120 d BSPL with a 63 d B signal-to-noise ratio and - 26 d BFS sensitivity. The MP34DT01 is available in a top-port, SMDpliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
