10.2.1.1 Example Measurement Schematic – Differential Input
A. TI recommends an external RC antialiasing low-pass filter for the CTSD16 to prevent aliasing of the input signal. The cutoff frequency should be <10 kHz for a 1-MHz modulator clock and OSR = 256. The cutoff frequency may be set to a lower frequency for applications that have lower bandwidth requirements. It is up to the user to determine the configuration and type of low-pass filter used.
