Reading pinouts

[JoeWawaw]

Hi, I've been trying to figure out the pinouts for a pressure sensor, the MPX5050DP (the one i have is the unibdoy package with dual ports), but the datasheet seems very ambiguous to me. Instead of risking it and possibly accidentally frying the sensor, i was wondering if someone tell me what the pinout for the sensor is. here's the datasheet: **broken link removed**
Thanks

What a mess. There are several unibody packages and some have 2 and other have 3 "types" with different pin outs.

Does this help:

How do you know if it is style 1, 2, or 3?

Here, Is this it?

Style 1: 1=Vout, 2=gnd, 3=Vcc, 4=V1, 5=V2, 6=Vex
Can you see the little nick on pin 1?

seems as though that would be the one, but then after figure 1 in the datasheet, it mentions that the unibody packages have no connection on pin 4,5,6
also, i have no clue what the pins V1 V2 and Vex does here

OK, so you only use pins 1, 2, 3 as Vout, Ground, and Vcc.

Nothing, they do nothing except provide mechanical support for the transducer when it is soldered to isolated pads on a circuit board.

Really? ok thanks a lot then! i'll try it out with that configuration
