Part Number: ADS124S06 Dear Sir, May I ask if Filter Response will mainly get impact from internal oscillator temperate deviation? I am estimating filter response using ADS1x4S0x Caluculator.xls. My idea is; I get Filter frequency response of Low-Latency Filter with 16.6SPS for example: I understand that 50Hz notch is centered when fCLK=4.0960MHz. I am keen to the internal oscillator will move the filter response, then I refer to the following internal oscillator spec and read min and max values of 28 samples in Figure 25. then below is summary; The accuracy of +/-1.5% will rigidly cover across PVT. Now I get filter response by changing max deviation of fCLK to 4.157MHz as follows; It is till -29.09dB attenuation for 50Hz line cycle. If there is another factor to consider which will impact the filter frequency response, please let me know. Best regards, Masa
