For the AD5241, can you program multiple AD5241 on the same SCL and SDA line? Or is that only possible for the AD5242 because it has dual channel? So if I have 2 AD5241, can I program both simultaneously or will I only be able to share the same communication line but I can only program 1 at a time?
You can program multiple AD5241 on the same SCL and SDA line. It is always recommended to program one device at a time which is sharing the same I2C lines.
