Other Parts Discussed in Thread: DAC8820
I am working on an application with the F288335 experimenter Kit using the ADC to read in a value and then output a processed value to a DAC8820. The connection to the DAC8820 is a parallel connection. The sampling rate of the ADC is 1MHz. The output rate is at about 100kHz.
There is excessive digital noise on the ground when the process is running. It is creating about +/-20mV on the ground. At every analog voltage source there are bypass capacitors of 10uF (electrolytic) and 0.1 uF (tantalum) to help reduce the noise.
Any suggestions on being able to reduce the noise?
