[sdiy] S&H

[Peter Grenader]

Kids,

I've just built a honey of a S+H using National's LF398.  You hang a tranny
and a very small compliment of res's, caps - and bang - seems to work just
fine.  Mine has an option of either a stepped output or a smoothed out,
which takes the first and runs it through a 1 meg pot-controlled RC to a
50uf cap nto op amp lag circuit.

works great.

Not very sophisticated, but i was in need one just one more sampling device
and this was painless and hums along like a bee.
