Hi Prakash,Let's work on problem 1 first. Are you using a LMP90100 eval board? I would like you to try the set up shown in the eval board user guide (available on the ti.com website) in section 3.0. Example #1: Quick Start – DC Reading. Even if you don't have the eval board you can set this up using components you have. Set VA to 5V, VIO to whatever the arduino is using, and VREF to either 4.1V or the 5V supply. Make sure all supplies are bypassed well. Connect the resistors R5, R17, and R21 to the 5V and connect your inputs across R17. Make sure you have caps like C12, C13, and C14 installed. Try making some measurements and see what results you get. Mike
