Simple 3 Input and Gate Comparator Wiring diagram Schematic
This is a Simple 3 Input and Gate Comparator Circuit Diagram. This schema has high output only when all three inputs are high. The non inverting-input current, when all three inputs are high, must exceed that of the inverting input, as determined by R4. The schema can be converted to a AND gate by transposing the two inputs of the op amp.

Simple Diode Feedback Comparator Wiring diagram Schematic
This is a Simple Diode Feedback Comparator Circuit Diagram. This schema can drive an LED display with constant current independently of wide power supply voltage changes. It can operate with a power supply range of at least 4V to 30V. With 10M resistances for R2 and R3 and the inverting input of the comparator grounded, the schema becomes an LED driver with very high input impedance. The schema can also be used in many other applications where a controllable constant current source is needed.

Simple Demo Comparator Wiring diagram Schematic
This is a Simple Demo Comparator Circuit Diagram. This schema is an op amp without a feedback resistor. R2 and R3 junction point sets the reference voltage. When the input voltage set by Rl is below the reference voltage the LED glows. If voltage is above reference, the LED goes off.
