Connect a filter capacitor to the SNSP pin to improve signal-to-noise performance of the signal path. Input noise with a frequency close to the ΔΣ modulator sampling frequency (typically 10MHz) is folded back into the low-frequency range by the modulator. The purpose of the RC filter is to attenuate high-frequency noise below the desired noise level of the measurement. In practice, a cutoff frequency that is two orders of magnitude lower than the modulator frequency yields good results.
The cutoff frequency of the input filter is determined by the internal sensing resistor R2 and the external filter capacitor C5. The cutoff frequency is calculated as 1 / (2 × π × R2 × C5).
