I have a battery powered application using the ADAS1000 ic for ECG AFE.
I am testing the application using ECG simulators.
When the simulator is powered using battery then my waveform's are clean, but when the simulator is powered from a DC adapter connected to AC supply, then I can observe some supply noise on my waveform's.
Any suggestions on how to mitigate the problem from the hardware side?.
The ECG circuit is similar to the EVAL-ADAS1000 circuit.
