I'm working on TMS 320F2808 Control Card. The issue that I'm facing is with ADCs; the digital values that I tend to get contains last 4-5 bit variations. Thus my ADC value is unstable which is in turn effecting my calculations. I've attached the waveform of the digital values from ADCINA2 of the card. Out of 12bits, last 2 bit variations is acceptable but not more. Here I'm getting around 13-20mv of variations. How do I reduce this variation to less than 1mV ???
