The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing 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 IMP34DT05 is a low-distortion digital microphone with a 64 d B signal-to-noise ratio and - 26 d BFS ±3 d B sensitivity. The IMP34DT05 is available in a top-port, SMD-pliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
