Only positive value output from voltage follower. What's wrong with it? Thank you!
I'm trying to use voltage follower in my system. But I find that no matter what input signal inputs to voltage follower, only positive part can be output from voltage follower. I'm confusing that if I set the voltage follower in wrong way or if there are some other setting of the board.
Here is the detail of my experiment:
I just used a voltage follower whose input+ is port 0 and output is port 0.
I also set the power of voltage follower to 'High power'.
In my code, I add 'Opamp_1_Start();' into for loop.
the input signal is sine wave with 1kHz, 1 Vpp and 0 offset.
But the output of voltage follower only have the positive-value part shown in attached picture.
I really want to know what's wrong with it? Thank you so much!
