Title: On off according to voltage?
Post by: Mercury on April 05, 2008, 12:52:10 PM
Hello forumers

I want to have an output that goes on and off according to an input voltage. The voltage is some mVolts. For example, between 100 and 200 mVolts it goes on and beyond those limits it goes off. What can i use?

One controller with analog input , and these controllers have at least two digital outputs.
( controllers types :  SHIMADEN , KIOUR , JUMO , etc  depends the money )

Window comparator...

Is one op-amp for low voltage level and in series another op-amp for high voltage lever. Together they make a window comparator.

Search here for the Voltage window switch (http://www.pcbheaven.com/handbook/archive/index.php?s=C&cat=Comparator)
