Description

The MP23DB01HP is an ultra-compact, low-

power, omnidirectional, digital MEMS microphone

built with a capacitive sensing element and an IC

interface with stereo operation capability.

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.
