IMP23ABSU vs MP23ABS1

[JKing.3]

Does anybody know if there is any difference between these two MEMS Microphones. The IMP23ABSU does have some Ultrasonic characteristics, but my understanding is the MEMS mics would have ultrasonic bandwidth anyway.

Thanks

Hi @JKing.3 ,

Their performances are pretty similar, the main difference is that the IMP23ABSU has been characterized in frequency response up to 80kHz (for ultrasound analysis, see AN5522) and it has been qualified for industrial applications, while the MP23ABS1 is recommended for consumer applications.
