hardware INA331IDGKT Cannot work in My Project

[ling1995]

Respected sir:

Good day. Recently I am resting in my home cause some reasons. I was boring and I decided to design circuit.I have a big interest in electronics. However, my professional knowledge is still limited. So here I am. but maybe it's simple for you.Please help me out!

 My situations are as followings:

I myself design a circuit,but it don't work ! I chose INA331IDGKT cause it's rail-to-rail output,low-cost and low-power.Why it can work in the ORCAD 16.3 ? I have already built the INA331IDGKT library files and symbols before I use it.If you need more details about hardware,please refer to the datasheet of INA331IDGKT.

Best regards~

You forgot to attach the schematic of your circuit for us to see anything wrong.
