Hi all,
I need to duplicate the voltage of a pwm. when 0.1v should out 0.2v; 0.4v - 0.8v; 1v - 2v; etc...
Im using a non inverting op amp with a pot for adjustment, but it doesnt work like it should.
Like, when is 0.2v the out is 0.3v and when 1v is 2.4v.
I've tried with tl071 and lm324 and they behave differently, but both not correctly.
Any tips?
