Supply noise on ADAS1000

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.
