Notes:

Characterized with an analog input sine wave = (FTP(maximum)/100). Example: FTP(maxium) = 1 Msps/100

= 10 KHz sine wave.

Sinewave peak amplitude = 96% ADC_ Full Scale amplitude input with 12-bit resolution.

Spec values collected under the following additional conditions:

12-bit resolution mode.

All registers at reset default value otherwise not mentioned.

ADC Measurements done with 3.3V VREF Voltage.

Value taken over 7 harmonics.

Referred to as AVDD in the pinout.
