ADC draining pressure sensor's Vout

I've been having issues with my pressure sensor (or so I thought). Whenever I hooked it up, the voltage of Vout started at around 3.3, and then gradually dropped to 1.6 (in about 20 seconds). I was puzzled, until I disconnected the wire going from vOut to the ADC's input channel. Then, the voltage was normal.
So I figured out the problem is the ADC. I ordered a new one.
Any suggestions of what went wrong???
Both items are getting the correct voltage and are hooked up correctly.
The pressure sensor is a Freescale MPX4115AP and the ADC is the LTC1298CN8
Thanks!!!
