8.2.4 Window Detector
Figure 29. Window Detector
A window detector monitors the input signal to determine if it falls between two voltage levels. Both outputs are true (high) when VREF1< VIN < VREF2
Figure 30. Window Detector Output Signal
The comparator outputs A and B are high only when VREF1< VIN < VREF2, or "within the window", where these are defined as:
Equation 11. VREF1 = R3/R1+R2+R3) × V+
Equation 12. VREF2 = R2+R3)/R1+R2+R3) × V+
To determine if the input signal falls outside of the two voltage levels, both inputs on each comparators can be reversed to invert the logic.
Other names for window detectors are: threshold detector, level detector, and amplitude trigger or detector.
