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.
The Acoustic Overload Point (AOP) for the MP23DB01HP is 120 dBSPL.
You can convert the PDM output to dBSPL using the formula dBSPL = dBFS + 118, based on a reference point of -24 dBFS for a 94 dBSPL signal at 1kHz.
A 94 dBSPL signal at 1kHz corresponds to -24 dBFS +/-1dB for the MP23DB01HP.
No, the frequency response of the MP23DB01HP is not flat.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
The REACH status is REACH Unaffected.
