hey all,
i want to buffer a voltage between 2 DC circuits with different grounds. a traditional op amp buffer won't work as i am not prepared to connect the 2 grounds together. what i would want is something like an optocoupler but with linear characteristics. can anyone suggest a method for doing this ????? (the voltage that i want to buffer is in the range of 0V to 5V. the buffered voltage will actually be an analog input to a PIC).
thanks in advance !!!!!!!!!!!
