AD7674 / Single/Differential  Ended Configuration

Question

For Differential circuit as shown below , datasheet says 
 " When provided an input signal of 0 to V REF , this configuration produces a differential ±V REF with midscale at V REF /2 " 
 For following configuration and different Analog input ranging from 0 to 4.096V as below: 
 1) Analog input 0V --> ADC count ? 
 2) Analog input 2.048V (Vref/2) --> ADC count ? 
 3) Analog input 4.096V (Vref) --> ADC count ?

Hi ETRX, 
 I'd like to confirm are you referring to output codes and input voltages? Please refer in the datasheet table 8 page17.

Hi ETRX, 
 Serial interface is different from parallel interface. In Serial interface the data is synchronized with the 18 sclk pulses valid on both rising and falling edge of the clock.
