AD noisy? (No)

The SDO112A fed the M5 with quite a clean signal and got something very noisy on the Oscillo @Calin made.
Is the AD input of the esp32 noisier than an stm32 or the old arduino, is this the amp that M5 hardware added?

After disconnecting the M5 from the computer and grounding the source, the sampled signal is very clean.
