    Hi all..

    I need your help, I'm still beginner in electrical.
    from my previous thread I got some advice to use Instrumentation amplifier to amplify the output of strain gages.
    and I choose ISL 28270/ 28470. I thought that one has already perfect to amplify my strain gages. but I don't know how is the circuit with ISL 28270/ 28470. Could anybody please help me with the circuit??

    I'll use the strain gages with supply 5 Volt, resistance 350 Ohm, and output from the strain gages less than 3 mVolt. supply for Instrumentation amplifier is 5 Volt.

    Thanks a lot for your help

    You can get application notes from Omega Engineering -

    They are a good source for information about strain gauges. Why did you select a dual instrumentation amp?
