1. Minimum ADC sample times are dependent on adequate charge transfer from the external driving circuit to the internal

sample capacitor. The time constant of the entire circuit must allow the sampling capacitor to charge within 1/2 LSB within

the sampling window. Refer to Figure 8 for models of the internal ADC circuit, and the values to use in external RC sizing

and calculating the sampling window duration.

2. Mode1: 6 sampling cycles + 10 conversion cycles at 13.33 MHz.

3. Mode2: 5 sampling cycles + 10 conversion cycles at 13.33 MHz.

4. Mode3: 6 sampling cycles + 10 conversion cycles at 16 MHz.

5. IADCREFH and IADCREFL are independent from ADC clock frequency. It depends on conversion rate: consumption is driven

by the transfer of charge between internal capacitances during the conversion.

6. Current parameter values are for a single ADC.
