On the bright side, TL084s are quite reasonably priced fuses, so perhaps an IC socket would be the best investment ;-) Heh! Both the original part and its replacement were pulled from an old pcb and
A ground strike is one of the most damaging mechanisms as it affects things some distance from the strike. A strike to ground induces large electric fields radially from the point of the strike as
Dear Bill, LF Group, It seems that a lightning strike has a current of 10s to 100s of kiloamperes, with a rise time measuresd in kiloamps per microsecond, so the transient E and H fields must be inte
Hi Bill once you get outside the spec area some devices perform somewhat oddly. Discrete transistors will take quite a lot of punishment if the actual energy is not too great...i.e high spikes but ve
Some years ago we had lightning strike a nearby lamp-post. All of the video recorders in the street were destroyed - except mine! I assumed that my earthed antenna formed a Faraday screen protecting
[..] You didnt say whether your op-amps were powered? ..... I suspect not but the generation of a large voltage across the loop might be enough to to lift the input to a destructive level, and decoup
