(10) This includes only +VA current. With +VBD = 5 V, +VBD current is typically 1 mA with a 10-pF load capacitance on the digital output
pins.
Measured using analog input circuit in Figure 51 and digital stimulus in Figure 56 and Figure 57 and reference voltage of 4.096 V.
Calculated on the first nine harmonics of the input frequency.
Can vary +/-30%.
