Hi everybody,
I would like to know if this will work properly? I didn't wanted to add any capacitors as long as supply is DC and input voltage is slowly varying. I just wanted to make a voltage follower (2nd opamp). I used the first one to make virtual ground. I didn't just connect one battery to Ucc+ and the second to Ucc-, because my batteries are rechargable and I'm not sure if the voltage is exactly the same.
In future, if my signal is too small (less than 2V) I would like to amplify it changing second opamp circuit to inverting with amplification of 3 or 4.
Thanks for answers.
Regards.
