    Can the AD-620 be used to amplify a triangular or sin wave. If yes how?

    Yes, if the signal frequency components are in the frequency response range of the amplifer. A triangle wave has high frequency Fourier components that must be amplified to accurately reproduce the waveform.

    If the frequency conditions are met then you just apply proper supply voltages to the amp, add a gain resistor for the desired gain, and connect the signal to the differential inputs. If you have a single-ended signal then connect the unused input to signal common.

    AD-620 is also an instrumentation amplifier. So I suggest some searching on Google using the term "instrumentation amplifier"
    Why do you want to use an instrumentation amplifier. We could give better help if you tell us what you want to do.

    I am creating a triangular wave using transistor and a Hex Schmitt Trigger.
    The frequency of my wave is between 20-30 kHz, but my amplitude is very low appoximately 330 mV. Thus I want to amplify it or can anyone tell me a better way to create a triangular wave of 20-30kHz and 3V amplitude
