ADuCM355 AIN4-AIN7

Hi Analog,

I've had problems finding information on how AIN4-AIN7 are connected internally in the ADuCM355. They are not included on any of the AFE die/switch matrix figures in UG-1262 or the Datasheet other than in "Figure 8. ADC Input Stages" in UG-1262, where it is shown as if AIN0-AIN7 are direct inputs to the ADC. In other figures, AIN0-AIN3 are a part of the switch matrix. 

Does this mean that AIN0-AIN3 are a part of the switch as seen in Figure 26, UG-1262, and that AIN4-AIN7 are direct inputs to the ADC with no other connection options?

Thanks!

Andreas
