Electrical SpecificationDSADC Parameters
12) Voltage V_CM is proportional to V_AREF, voltage V_CMH is proportional to V_DDM.
13) The modulator needs to settle after being switched on and after leaving the overdrive state.
14) SFDR = 20 * log(INL / 2^N)
The following DSADC parameter are valid for V_DDM = 2.97 V to 4.5 V.
