xc43 referance voltage

Ed Schippers 8 months ago in Expansion modules / XC4x updated by Kerry 8 months ago 1

On the XC4x serie there are multiple Vref+ and Vref- and on both C1 and C2 

Are these interaly connected in the module? 

Or are they seperate from eachother and serve only dedicated Vin's?

Best Regards Ed

Hi Ed, the Vref's are separate.  When using to power a device connected to a particular input, say a VIN, you have the capability of selecting which +Vref is associated with that input channel. (Reference voltage selection) If the selected +Vref has an error, then the input channels associated with it would take on their error value.
