Hi there,


Currently I'm looking which ADC to use in combination with my Altera Stratix V device. I've tried to make an overview of 3 different Analog ADC, but would like to check if I understood/interpreted the datasheets correctly. I would like to use the device to their full potential. So max sampling speed and if it is a dual ADC both channels.


Thank you for your help!


With kind regards,
