My professor gave me a chip which is a MC1488L I have no idea what tha tis... so i'll get that done asap hopefully. As well as MAX232... wahtever that is... so far... the simplest one I've gotten is the OpAmp solution...
Considering I've suggested just a simple capacitor twice, I don't see how the simplest suggestion you've had is an opamp?.
From what I can remember, an MC1488L is an RS232 interface chip, but from your requirements that you have mentioned so far, you've never mentioned a requirement for that?. Is your actual requirement more than you've asked for?.
