hi all,
I am trying to design a voltage follower circuit. The input is quite low, around 0.8 - 0.9V.
I tried an OP, whose power supply is +/-16V, then connected the output with inverting-input, and connected the non-inverting-input with my input (0.8 - 0.9V). But the output does not follow the input, and actually the output is around 1.4+V.
The circuit does not work well. I guess it is due to the input is too low. Am I right? So what OP should I use then? Any comment is welcome.
Thanks a lot.
