Original question:
Tool/software:
Regarding the characteristics of the Digital filter, please let me know the Pass band, stop band, attenation ，Thank you
Hi Zhenmin,
The ADS1014-Q1 implements a Sinc digital filter, and is a single-cycle settling ADC.
You can read more about digital filter types in ADC's from the following app note: Digital Filter Types in Delta-Sigma ADCs (Rev. A) (ti.com)
I would also recommend taking a look at our TIPL series: Precision labs series: Analog-to-digital converters (ADCs) | TI.com
Particularly the first two videos to gain a better understanding of how the delta-sigma topology for ADCs works, and the video titled 'Aliasing and anti-aliasing filters' to gain a better understanding of what the diagram from figure 26 is showing, and why implementing an anti-aliasing analog input filter is important for keeping any frequency components in the input signal around the modulator frequency from aliasing back into the pass band.
Best Regards,
Angel
