Overview: MP34DT05-A Datasheet MEMS audio sensor omnidirectional digital microphone Product status link MP34DT05-A Product summary Order code MP34DT05TR-A Temperature range [°C] -40 to +85 Package HCLGA 4LD (3 x 4 x 1 mm) Packing.

General Description

The MP34DT05-A is an ultra-pact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface.

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.
