i am using to amplify a 1mv signal with the analog instrumentation amplifier
Ad 620
with + 12v/ -12 v power supply , gain resistance i used was
10 Ω
it worked very good for one day , i get very good result but after two days , whenever i On the circuit , it gives the sine way for some time of the desired amplitude
but after the some time its gain decreases and also the wave form gets clipped on both the sides
i replaced the power supply , but the behavior of the cck did not changed
can any one tell me what is going on , and what could be the problem
