Characteristic dimensions of the inner silicon plate in the MPX5010DP sensor

Hi,

Does anyone have information on the size (surface and thickness) of the active part of the silicon plate which acts as a membrane for pressure measurement?

Thanks

Hi Jean-Luc,

we have an application note dealing with output noise and recommended techniques to mitigate the output oscillations. Please find it attached.

With Best Regards,

Jozef

Thanks Josef.

I test the response of this sensor to a pressure step and I observe damped oscillations of the output voltage. The frequency is about 100 Hz. This frequency seems a little low when I compare it to the natural frequency of a silicon membrane of 1mm^2 x 0.001mm which is of the order of 2500 Hz. Have you ever known of such oscillations?

Sincerely,

Hi Jean-Luc,

I have checked available documents and older cases. Unfortunately I couldn't the requested MPX5010DP inner silicone plate size. We do not have this value.

I apologize for inconvenience.

With Best Regards,

Jozef
