I would like to implement a current signal conditioning circuit to be an i/p to the ADC of Motorolla HC12, So I need proper protection in this circuit which was proposed to be an Isolating transformer (i.e galvanic isloation)..so I need an Isolating transformer codes and datasheets so that I can purchase it in Egypt, it should be 5 V at least with unity turns ratio or something like that...
I searched on the internet but found 220 V i/p transformers which is much more larger than the one I need..
Can anybody help me?? and Does anyone have an advanced idea to protect the ADC from over signals other than this idea??
Thanx in advance![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
