I am using an AD9059 to convert analog to digital.
Right now the input voltage is 2.5v, how to make it to be able to measure higher voltages?
I could add a mechanical dial with resistors that lower the voltage to 2.5v, but I was wondering if it's possible to do it digitally. like for example to change the input max voltage using a microcontroller? Let's say to make it measure up to 1000v ?
Here you can see the schematic of what I have right now:
