I recently received a few AD 8065 and 8066 chips that I had ordered. To simply test them, I soldered them and wired up a simple buffer on a breadboard. The output showed a lot of oscillations of around 300 MHz. The same thing happened when I wired up an op-amp negative feedback circuit of gain 2.
The output read for wither circuit is highly arbitrary (at least, it seems so to me), and I haven't been able to reproduce my results. But the oscillations persist.
Why is this happening? What can I do? Are my chips faulty, or am I using them wrong?
Please do help! Thanks in advance!
