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. 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. 3. Current parameter values are for a single ADC. Table 28. ADC-Comparator electrical specification (continued) Symbol C Parameter Conditions Value Unit Min Max |
