Seriously this looks like a nice HV opamp.

(well if you download the spec sheet the open loop phase does a dipsy
doodle at a few hundred kHz.)

I can replace some expensive Apex parts.
(as soon as someone has stock.)

Just what PH needs- 140V across 50G is the same as 3V across 1G,
right?

Thanks for the heads-up - looks to be worth further investigation.
It doesn't have the same output-capacitance load requirement of most of
the Apex parts {many seemingly designed to drive piezo crystals} - that's
not necessarily a bad thing.

Well, I use the Apex to drive a piezo stack... maybe the LT part won't
be as good? I'd have to redo the pcb... or make an Apex header pcb.

I assume that a nice email to LT would get me some free samples.

    With, or without "The Steep Canyon Rangers"?

?? It was meant as a parody of "The new phone book's here....etc."

George H. (I'm clueless most of the time.)

 

[Spehro Pefhany]

Yup, except for the 11 nV noise and 15-ish pF input capacitance, which
would put it a good 30 dB off the pace, unfortunately.

Wasn't thinking of using their front end without some low-noise gain
up front.. but in seriousness I think you'd have to watch out for that
resistor's voltage coefficient, if linearity mattered.

   So, you don't know about "Steve Martin & The Steep Canyon Rangers",
his Bluegrass group?

I guess I knew he played the banjo.

Of course the master died just last year... RIP Earl (Scruggs)
My son likes the banjo so we have a few of his CD's

I'll have to stick with an Apex part until someone else makes a device that
will output -20 to +150 that my piezo actuator needs...
So near yet so far (rats!)

I think Bela Fleck is the new master, he just plays jazz instead.

Bela Fleck has a Jazz band and a traditional bluegrass band.

Oh! OK. What is that bluegrass band called?
