Hi,
Now we are using ADS5562 chip sample signal, it will covert the INP/INM differential signal into digital data. My question is that
-Chip separately covert INP & INM 2 analog into 2 digital data, and then INP's digital data - INM's digital data, and then output digital data to chip outside?
-Or chip do "INP analog - INM analog" into one single signal, and then convert single analog signal into digital data, and then output digital data to chip outside?
-Actually I can't understand that Figure 45 of datasheet, differential sample and hold architecture. There are INP, INM, but I don't know how work sampling switches on top and bottom?Where is interface of the differential sample and hold architecture for 16bit-ADC?
Best Regards,
Kent
