OP amp help
I am using a 741 op amp to try and amplify a low dc voltage.
+ = 5vdc
- = 0v
+ non inverting input = 0 to 0.8vdc
- inverting input = 100k to 0v / 20k to Output
No matter what I try I get around 4.2 to 4.6 on the output even if I use 0 feedback.
I would like to amplify a range 0 to 0.8v to a 0 to 5v range, please help.
