Hi

Pretty basic question. I am trying to generate a sinusoidal signal but I am unsure of the best op-amp to use. Any pointers?

I am also using PSpice to simulate the circuit, if any one knows a suitable op-amp that can be used in PSpice

Thanks
Milan

I would point to... details! =) Voltage? Frequency?

Its a small voltage. Looking for 5Vp-p and producing a 50kHz signal.

Ca3080 .

Or you could use one transistor and a phase shift network.

thanks for the replies. Are there any other parts I could use? I cant get access to a Ca3080 and im not sure how to use the phase shift network. Would a LM4041 work?

That's a silly question, the LM4041 is not an op-amp.
