Hi
I am trying to draw the circuit of a comparator that produces in the output 5.4V and -4V when the input voltage is inferior or superior to 1.5V.
Should i use and histerisis comparator like the one in the figure?
I know that for this montage
V0=VCC
V+=Vcc(R2/(R2+1))+Vi(R1/(R1+R2))
Vi=-Vcc(R2/R1)
Vo=-VCC
Vi=Vcc(R2/R1)
Then chosing that resistor i could get the reference point for comuting,the problem is that the output would be equal to Vcc or -Vcc and not to 5.4V or -4V,right?
Thanks
