3 AD7280As serial daisy chain connection, like Figure 29 of datasheet Rev0 p18/48.
I would like to control the voltage of these 3 cells similarly.
But the current value was different.
Master,bottom,< Slave, top < Slave, mid.
1: Why do three devices become a different current value?
2:Can we calculate or measure each device current value when these are communicating?
3: Is the difference of current between Master and Slave the current of communication lines ?
What is the cause of this difference?
4: How to control the current of these cells similarly.
5: Can we know these current variation? ,min & std div.
