    Gain higher than 50 for PGA component

    daniel.caliari

      Hello Everybody,

         

      I am dealing with very very small signals ( something near the mV or uV scale) and I need amplify it using an PGA. The problem is that the maximum gain available is 50 and it still not enough. I already tried to connect one PGA output in the input of another, but the results were totally unexpected and something random ( at least for me) even when both gain were just 1. Someone has some hint what is happening or what can be done?
