Why the Voltage drops from DAC ?
Hello Every body,
I am generating 3Vp-p from DAC inside PSOC 5LP. It looks very nice as long as i do not connect it with bridge (in order to excite the bridge). When i connect it, the voltage drops from 3 to 1/3 of that. I tried to place a voltage follower at the output of the DAC but as a result my signal becomes very noise and drops too (but not much).
I am failed to find the reason. Can any body have any idea?
I attached the snap shot of my design.
Looking forward for your suggestions.
