Thanks, Magnus.
The phrase "The JPL units use a ua709-type operational amplifier to
allow a high switching speed with low noise" makes me thing a lot about
how the concepts "high switching speed" and "low noise" have changed
with time :)
Ah.. the venerable 709.. As a kid fooling around with opamps in the
early 70s, I was SO happy when they came out with the 741 and didn't
have to deal with compensation. Finally, circuits that weren't
oscillators!
I only heard of the 709 and saw some... I already started with the 741
in the early 80s :) (both discovering our ages...)

Javier
