    Datasheets will give you the info then YOU decide. There are too many combinations to give you an answer/

    How about a subject? (Use the pencil icon on the original post)

    First, you need to replace the ARM with a Prop.

    Then, we need more info on the load cell (as Stephen indicated). Is the load cell already amplified? Does it have a built in Wheatstone Bridge?

    Normally, you don't just connect the load cell to a ADC, but there is some external cricuitry (either outside the load cell, or built into it).
