Figure 9-5 Antialias Filtering

For signal conditioning in ADC applications, make sure to limit the input frequency to the ADC. Low-pass filters can prevent the aliasing of the high-frequency noise with the frequency of operation. This design example shows a method by which the noise can be filtered in the THS413x. Figure 9-5 shows the design example for the THS413x in active low-pass filter topology driving an ADC.
