Dear community,
We have been developing our product with MMA8652.

We hope to use the MMA8652 on Low pressure environment ( 472mbar ) .

A 472mbar is equivalent to altitude degree of 6000m.

[Question]
   Are there any problem using in such a environment ?

   We could not find a note in MMA8652 data sheet.

Best Regards,
Koichi Sakagami

Hi Koichi Sakagami,

We don’t have any evaluation done at such low pressure environment.

But, according to our chief engineer, since the g-cell is hermetically sealed at the bond pressure it is not affected by the ambient pressure changes. So, operating at a lower pressure should not affect the pressure in the g-cell and therefore will not affect the performance.


Have a great day,
Jose
