[sdiy] Sample and Hold

[René Schmitz]

Hi Elain,

here is my take on the LF398:

The thing worth noting is the logic input, which requires some care if 
you do not have a 0 to 5V TTL signal to trigger it. One way or another 
you need some resistors to get the pulse into shape or bias the logic 
reference.

Best,
  René
