This circuit protects an operational amplifier with respect to both current and voltage. The circuit is from American documentation and can be applied to almost any operational.
In the figure we have the way to obtain an adjustable 1 to 10 mAconstant current source. The...
We found this circuit in an old General Electric documentation. In fact, PUTs are not common...
This alarm uses several sensors that directly trigger a sensitive relay. A larger relay can be...
