ADVANCE INFORMATION for pre-production products; subject to change without notice.
Depending on the input characteristics of the ADC, an external CFILTER may be required. The value of CFILTER depends on the size of the sampling capacitor (CSAMPLE) and the sampling frequency while observing a maximum CLOAD of 1000 pF. The capacitor requirements can vary because the input stages of all ADCs are not identical. Figure 12 shows a general ADC application as an example only.
