MP34DT05TR-A

MP34DT05TR-A is a MEMS audio sensor omnidirectional digital microphone. This is an ultra-compact, 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. The MP34DT05-A is a low-distortion digital microphone with a 64dB SNR and -26dBFS ±3dB sensitivity. Typical applications include mobile terminals, laptop and notebook computers, portable media players, VOIP, speech recognition, A/V elearning devices, gaming and virtual reality input devices, digital still and video cameras and antitheft systems.
