This is your classic Sample and Hold.
Signal goes in - trip the threshold on the Pulse In - and the out will "hold" the voltage at the point when you triggered it.
There is a separate White Noise circuit. It is normalled to the S+H Input for all your random needs. There is also a Noise out so you can access it independently as well.
There is a slew knob so you can smooth and lag your output to taste
Current Draw: +12V = 23mA, -12V = -12mA
