Note1: Internal protection diodes clamp the analog input to VDD_IOB and VSS.

These diodes allow the analog input to swing from (VSS-0.3V) to

(V33_ADC+0.3V) without causing damage to the devices.

Note2: LSB means Least Significant Bit.

With VINL = 2.6V, 1LSB = 2.6V/2^12 = 0.635mV.

Note4: ENOB = (SINAD-1.76)/6.02.
