Description

Description

The MP23DB02MM is an ultracompact, 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.
