[sdiy] Uses for CA3039?

[mike ruberto]

Thats very interesting! I've never heard of Ken Gale before. Not a
whole lot about him from Google searches either. Any ideas about where
I can look to learn more?

I was studying the datasheet last night and noticed the pin marked
substrate. Does this need to be tied to a rail for proper operation
like with a 3046? Anybody know?

Thanks

Mike
