For my morphing Programmer I need more accurate levels
to crossfade between than in my Interpolating Scanner. After
some thoughts about Zener diodes or opamp-enhanced
clamping diodes I finally decided to use voltage references
to keep levels constant. I found the TL-431 to be what I need:
precise, low tempco, small (3-pin) and cheap (about 1 $).
Anyway, there's still the question of stability. The data book
shows the capacitive load for which it is stable; but I wonder
if I can also use it in the feedback loop of an opamp, just
like an ordinary zener diode, without the opamp starting to
become an oscillator.
Yes, I might calculate it, or more likely just use it straight
forward without feedback, but maybe someone else has
already tried this?
Any experience in this, anybody? Any ideas?
