  • RE: INA125: What is the recommended way for balancing or 'Zeroing' inputs from a strain-gauge Wheatstone bridge into or through an INA125 or similar?

    Resolved
    Hi Rodrigo, ~100uN is approx. 100mg of weight or force. It is like a micro balance scale. Anyway, can you try our INA821 , INA828 , INA819 or INA818 Instrumentation amplifiers (IA), which are better to handle this level of sensitivity. Enclosed is a link about…
