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
