I'm an amature at this, so it's likely I'm misunderstanding the level shifting, but here is my issue: I'm trying to take a sine wave from the analog out of a teency board, shift it down, and then amplify it. The idea is to take the wave of 0V to 3.3V and convert it to be within -12V to +12V. This works in the simulation, but when I build a physical version, the top of the wave is clipped above 0V. I see this when probing the two places marked in the circuit. Any ideas or suggestions? |
