Dual limit comparator

Posted on May 18, 2012

This circuit gives a positive output when the input voltage exceeds 8 volts. Between these limits the output is negative. The positive limit point is determined by the ratio of Rl, R2, and the negative point by Rl, R3. The forward voltage drop across the diodes must be allowed for. The output may be inverted by reversing the inputs to the op amp
