I have planned to use 16 Channel ADC( AD7490) in my design. i have an query regarding this component,
1. What is the Required input current for the AD7490 REFin Pin?.
2. I have planned to use five AD7490 ADC in my design, for the Reference voltage generation i am planning to use AD780AR, Single Reference voltage generator(AD780AR) is enough for five ADC's or i have to use individual voltage reference generator for individual ADC.
