描述 Description

The MP23DB02MM is an ultra-compact, low-power, omnidirectional, digital MEMS

microphone built with a capacitive sensing element and an IC interface with optional

stereo configuration.

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 MP23DB02MM offers multiple performance modes enabled by different clock

frequency ranges (power-down, low-power and normal mode). The device has a

narrow sensitivity range of ±1 dB, high SNR and low distortion for all operative

modes.

The MP23DB02MM is available in a bottom-port, SMD-compliant, EMI-shielded

package and is guaranteed to operate over an extended temperature range from

-40 °C to +85 °C.

Applications

• Smartphones and handsets

• Laptop and notebook computers

• Wearable devices

• Digital still and video cameras

• Antitheft systems
