[sdiy] OT: High voltage diff amp

[Antti Huovilainen]

Hi

I have a signal (few volts) riding on top of high common mode voltage (few 
hundreds of volts). I need to isolate only the differential signal. Any 
advice on how I should approach this?

It's relatively low frequency (basically pulsed DC). Super-low cost is not 
a requirement but I'd prefer to keep the unit affordable.
