hello,
I have a circuit using an AD835, I am using it to do AM modulation the output is good. But I need to amplify that signal to 12v pk-pk. I added the LM7171 just as in this circuit: https://daumemo.com/final-pcb-for-the-diy-waveform-generator-part-10/
But when I hook up the output of my AD835 to the LM 7171, The signal from the source looses its negative part. and amplyfies only the positice, here is a picture before and after I hook up the LM7171.
Anyone has any ideas to resolve the issue and get full wave (-12 to +12) and no 0 to 12v ?
