I'm trying to create 10 electronically controlled variable resistors.
The intended voltage range will be 0-600v at about 0-100ma.
I'm using a microcontroller to linearize the output voltage based upon voltage feedback to an ADC.
I thought about using a vactrol but from my understanding they don't have a wide range of resistances and they don't react very fast.
SIC Jfets seem to be the only other thing I can think of but I'm not sure how they will work in this situation.
