Which NXP pressure sensor to use for -20 in hg - 25 psi that will compensate for changes in altitude?

Basically, needing something that will measure vacuum and pressure in the -20 in hg - 25 psi range, and will also compensate for altitude. The range can be expanded. At least 0.1 resolution.

 

Price is a factor as this will used on a production board. 0-4.7v output range if possible. (Digital is an option but not preferred)

 

My pressure sensor knowledge is not that great. Seems I may want vented? We currently use the MPXH6400 in our design but it is sealed, which from what I can tell does not compensate for changes in atmosphere.

 

Please also link the 3d STEP model as well. (I wish I knew how you guys were finding these)

 

Cheers!
