Sorry, I was Wrong when I said :

I remember that C6 has been suggested by you. I should have had confused when you have said : "Kai" said:
So, just connect the output of a LM741 (or similar) to superimpose the offset. But, again, don't forget the caps to ground. I just got that when i was rereading what you said in the original thread. There you meant to connect the Caps at the output of 741 and at Inverting Input of AD844, But I thought you meant to add a 100n Cap at Inverting input of the 741 ! So to conclude, based on your last reply , - I have to desolder the C6(The 100n Cap at 741's Inverting Input) - Cut the Direct feedback trace on the PCB (which needs desoldering the SMT 741 :( ) - Place a 10K resistor and a 100n Cap like the Figure 6 of the OP113's Datasheet ? - And lowering the R8 to 100 Ohm Thanks Again for your priceless helps , Farshid |
