1) According data sheet of AFE5808 , by default the ADC is capable of generating 14 bit signed 2's complement. It can also be configured to 12 bit. Am i right? The device is, but the EVM GUI might set it to offset binary by default. Yes, it can be 12-bit as well. 2) I configured the AFE as 16x serialization data rate (3[14:13]=01), 14 bit ADC resolution (4[1]=0), Using TSW1400 for ADC signal capturing and ultrasound echo signal at input then after saving the capture into csv file, I observed the ADC codes are b/w -32768 to 32767. But here my doubt is the range should be b/w -8192 to 8191 for 16x or 14x serialization rate, because the ADC resolution is 14 bit (ADC values are b/w -8192 to 8191). In 16x mode, two 0's are added. No, in 16x mode, the 0s are added to the LSBs, therefore the scale will shift. The new scale will be 64k wide instead of 16k wide, independent of the ADC resolution. How the 14bit ADC data is serially sent out in 16x mode? Here 16 bit means 16x
