ADAR7251 functionality

Hi guys,

 

1) I need some informations about internal voltage reference. In the datasheet there is only information that internal voltage reference is equal to 1.5V and can be overdriven externally if required.

I'd like to connect differential signals AINXp, AINXn = 2.4V, Vcm=1.2V.

So, do I have to connect external reference voltage then?

 

2) Are DC measurements possible?

 

3) I'd like to know what is the function of FAULT pin? In what conditions this pin become active?

I found only: This pin can be used as an interrupt input to the microcontroller or DSP in case of faults.

 

Thanks for any reply.
