Hello?
As far as I know Vref is the range of voltages convertible to digital value by ADC.
However, in case of AD9609, Vpp can be changed from 1.0 to 2.0V.
If you look at datasheet table 11, it says that if you change the value of address 0x18, Vpp can be changed from 1.0 to 2.0V. At this point, Vref is fixed at 1V.
Please let me know how this works.
Thank you.
