Hello
I want to conver a 0-10Vdc signal to 0-2.5 Vdc .I do it by two resistor (1%)as a passive voltage divider,Both the linearity is not good and in some region of full range the value of nonlinearity is high.If I use a .01% resistors the problem may be solved but the cost is too high.
I need to know is there an active solution with opamp for this problem ,(with using 1% resistors and precision opamps ) .
How to reach a precision divider with excellent linearity (max nonlin 2 mV at 10V)?
Regards
