They can be used in the places where you need to compare two voltages... Generally they are implemented using opamps...and its main application will be in almost all fields...

Here's something I designed for a ships rudder indicator.

First copy what is below, then go to Circuit Simulator Applet , click file>import and then paste>click import. And you should see it come up.

man its used to campare 2 voltages.assume voltage a and b.So suppose we are implementating it with an opamp.then suppose a is given to noninverting and b to inverting.if a is more than b we get output positive sat .if b is more than a , we get negative sat.applications Can be like cutout circuits Which cut out output if input voltage exceeds some reference voltage.got ?
