Other Parts Discussed in Thread: TL084
Hi all,
I'm doing a project and faced some problem with ADC of F2812. The feedback signal is a voltage 50Hz and 1.0V magnitude. I have used Opam TL084 to amplify and add 1.5V DC to the feekback signal.
The problem is when I measured directly the signal in ossciloscope, it's quite good. But when I connected the signal to DSP and read the value in graphic window of CCS 3.3 there are large noise amount accompany with the main signal, the peak value of noise is about 0.2V. And this noise also orrcured when I run at standalone mode and it make my system out of control.
Please help me solve this problem.
Thank you in advance.
Hoang Cuong.
