You are certainly a newbie. The key is to do this not with just an op amp but to also have the appropriate feed back network. This is a quick sketch of the type of circuit you need.

This is the basic circuit for the voltage gain you want. I happen to choose a not very fast op amp but I didn't know what chips you had available. Your problem maybe though what kind of load you are driving or a host of other details that you haven't specified. I realize you may not grasp all of the details, but here are a few details that will permit us to help you.

• Output load, what are you driving to 5 volts? Some possible choices; a computer or instrumentation input device, a speaker, a headphone.
• What voltage power supplies do you have to drive the amplifier? (You will notice my schematic does not show this mandatory supply.) +/- 15V, +5, two AA batteries
• Is your input and output voltage a peak, peak to peak or RMS voltage?
• I chose a 2K input impedance. Is this acceptable for your signal source?
• Lastly, you say you are having trouble using an op amp. What kind of trouble are you having?
