For a personal project, I’m trying to record ultrasonic sound. I would like to find the best way to record from 20kHz to 200kHz.

As I found from Wikipedia, animals can hear up to 200kHz.

As I prefer to design my own board, the best component I have found is this Knowles SPH0641LU4H-1.

But the range is from 50Hz to 80kHz...

What is the best configurations/components to record ultrasonic sound?

  • \$\begingroup\$ You're question can't be understood without following links. It should contain enough information that the question can stand on its own - even after the links die. Can you improve it by adding an image and the essential details from the specification? \$\endgroup\$ – Transistor Feb 29 at 19:43
