Hello , I am planning to use AMC1200 in voltage measurement , there are going to be 2 different ranges 1000Vpeak range and 100Vpeak range.
A relay is used to switch voltage divider branches in order to switch between ranges.
The schematic for the voltage measurement section is shown in the following figure , I 've used TIDA000555 from texas instruments as reference design.
The AMC1200 input is going to be +/-250mV for both ranges so it's output will be 4V p-p which is then signal conditioned to be from 0 to 3.3V around 1.65V offset
Any opinions or comments on the schematic?
Thank you very much in advance.
