-1PSI ~ 1PSI?

[patricksebastien]

Hi Chip.
I am trying my luck here, I posted this question on your blog.

I am trying to find the best pressure sensor and I came across this model: ABP2DRRT001PDAA3XX - the pressure sensor is -1PSI ~ 1PSI Differential. I am not sure to understand the differential part (there are 2 ports on the chip), does it means that the sensor can detect suction up to -1PSI? but how would that be represented on the voltage out pin (rated from
0.33 V ~ 2.97 V).
