(Equation 1) Ts ( Rin + Rext ) × Cin × 9<br />
Ts : Sampling time<br />
Rin : input resistance of A/D = 0.93kΩ 4.5 AVCC 5.5<br />
input resistance of A/D = 2.04kΩ 2.7 AVCC < 4.5<br />
Cin : input capacity of A/D = 14.5pF 2.7 AVCC 5.5<br />
Rext : Output impedance of external circuit<br />
(Equation 2) Tc = Tcck × 14<br />
Tc : Compare time<br />
Tcck : Comrare clock cycle<br />
