Description

The MP23DB01HP 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 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 MP23DB01HP offers multiple performance modes (power-down, low-power and

performance mode) enabled by different clock frequency ranges. The device has a

very high AOP in performance mode, sensitivity range of ±1 dB and high SNR for all

operative modes.

The MP23DB01HP 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.
