Hi
I am using lmv881 in order to generate a 10 Hz 2.5V sin wave - (2.5*abs(sin(2*pi*10*t)))
I connected the the amp according to the picture below (20ohm + 230uH is my load).
from my simulation I have seen that this should be working
when I connect it to my circuit it worked without the load but when connecting the load the Vdd starts to noise and jump in the same freq the sin wave (10 Hz) this influence my whole circuit and this 10 Hz noise reflected on any signal in the circuit .
why is that happening? and how can I fix it?
