Hi,
For this circuit:
For measuring the "120VAC-x" signals at 200kHz bandwidth what would a good way to do this?
So far for possible methods I have, voltage divider to opamp/ADC, optically isolated error amplifier, ie. FOD2741BSDV
isolation barrier opamp (transformer based or capacitive): ie. AD215BY (transformer chopper based)
ie. ISO122 (capacitive coupled)
I think making a circuit like the AD215 might be the way to go, or maybe just a simple resistor divider could work too.
cheers, Jamie
