"A new opamp's here, a new opamp's here!"

(Title said in the voice of Steve Martin)
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.)

Oops I screwed up the link.

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.

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

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.

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.

?-)

 

Oh! OK. What is that bluegrass band called?
