The frequency response repeats at multiples of the modulator sampling frequency of 76.8kHz. The overall response is that of a low-pass filter with a –3dB cutoff frequency of 3.32Hz with the SPEED pin tied low (10SPS data rate) and 11.64Hz with the SPEED pin tied high (80SPS data rate). To help see the response at lower frequencies, Figure 4(a) illustrates the nominal response out to 100Hz, when the data rate = 10SPS. Notice that signals at multiples of 10Hz are rejected, and therefore simultaneous rejection of 50Hz and 60Hz is achieved. The benefit of using a sinc4 filter is that every frequency notch has four zeros on the same location. This response, combined with the low drift internal oscillator, provides an excellent normal-mode rejection of line-cycle interference. Figure 4(b) zooms in on the 50Hz and 60Hz notches with the SPEED pin tied low (10SPS data rate). Figure 4.
