Please refrain from linking us to that really boring stuff.
I have told you time and again that your work makes me ill,
very boring pedestrian stuff.
and this is almost done, except for the idiotic TI opamp
problems:
What's the problem with the 'TI opamp'? Tell us something
interesting.
Yes, I seem to remember that was discussed on
another thread, right John?
Yup. THS3062, practically a unique opamp, blinding fast with +-15
supplies. But if it's amplifying a sine wave at, say, 20 volts p-p
out, and the frequency goes up to roughly 12 MHz, it crashes, pulls
tons of power, gets red hot, and phase inverts! If you drop the input
signal way down, it recovers!
We've been pestering TI support about this for about 6 weeks now. All
they say is that they don't have an engineer available to look into
the problem. Sounds bad.
