8.2.1.2 Detailed Design Procedure

Depending on the input characteristics of the ADC, an external C_FILTER may be required. The value of C_FILTER depends on the size of the sampling capacitor (C_SAMPLE) and the sampling frequency while observing a maximum C_LOAD of 1000 pF. The capacitor requirements can vary because the input stages of all ADCs are not identical. Figure 13 shows a general ADC application as an example only.
