I'm looking for ADC of 14 bit, with two channels simultaneous sampling. Sampling rate has to be over 100 until saveral handreds of ksps, and input signals are single-ended and unipolar voltage from 0 to 3.3V. However, I could only find ADC with differential input among ADI products. I know single-ended-to-differential conversion circuitry can be placed between signal source and ADC, however at the same time, another manufacturer is making single-end input ADC along with above requirements.
So question is, is there any merit to place single-ended-to-differential ADC driver before differential input ADC, compare to be using single-ended input ADC directly from signal source ?
Please presume single-ended input ADC is allowed to be input range of 0 to 3.3V, so no need to level shift, and also in case there is basically no need to amplify or attenuate the source signal.
Any of your instructions/suggestions are always very much appreciated.
