Hi All ive had a look around but cant seem to find any answers for what im trying to do i have a signal that basically goes from 5v to 0v and i need to invert it to 0v to 5v i have used a simple inverting op amp circuit based on an lm741 the actual input voltages are 4.8v to 0.9v and i cant quite get the output to reflect that properly. i have changed the input resistor to change the high output side, and that is now up to 4.5v and that is good. i cannot however get the low output side to drop under 1v attatched is a diagram with what i have any help would be awesome cheers
