## Description

The STMicroelectronics MP23DB01HP is a MEMS (Micro-Electro-Mechanical System) audio sensor designed for various audio capture applications. It provides a PDM (Pulse Density Modulation) output, which is a digital audio stream.

A key specification is its Acoustic Overload Point (AOP) of 120 dBSPL, indicating its capability to handle high sound pressure levels without distortion. The sensor also has a reference point where a 94 dBSPL signal at 1kHz registers at -24 dBFS, allowing for conversion to dBSPL values using the formula dBSPL = dBFS + 118.

This sensor is suitable for applications requiring accurate sound level measurements. For precise measurements, using the RMS value of a data segment is recommended, and a one-point calibration can further enhance accuracy. Keep in mind that the frequency response is not flat, meaning signals of the same dBSPL but different frequencies may appear with different dBFS values.
