This voltage comparator circuit gives a positive output when the input voltage is a positive or negative more than 8.5V.
But in between that the output is negative voltage.
The positive limit point is defined by the ratio of R1, R2, and the negative point by R1, R3.
The forward voltage drop across the diodes must be allowed from it before.
The output may be inverted by reversing the inputs to the operational amplifier IC1, that LM709 is used without frequency offset.
