Hello,
I am trying to create a function generator which produces a sinewave upto 1 MHz.
I have utilized AD9833 for generating sinewave. but this IC gives output of 0.6V and that to with a DC level of 0.3V. I am amplifying this sinewave with OP37 opamp. I have created a non inverting amplifier with Ri=10k and Rf=75k.I am facing difficulties after 200KHz. The amplitude starts distorting at the peaks and finally it becomes triangular wave at 1MHz.
Please suggest me some solution
