"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.

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.

With, or with "The Steep Canyon Rangers"?

With, or without "The Steep Canyon Rangers"?

I assume that a nice email to LT would get me some free samples. (no time at the moment)

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

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

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.

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

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 grew up on Lester Flatt and Earl Scruggs...

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!)

The group played on the Opry the first time I heard them. I hadn't heard anything about Steve Martin for at least a decade.

Another was Joe Mullins & 'The Radio Rangers'. He is the son of a country & Bluegrass DJ I knew when I was growing up. Paul, AKA: 'Moon Mullins' who played banjo in the early days of Bluegrass. He was about my dad's age, and they were from the same town.

I always loved 'Earl's Breakdown'.

Rangers",

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

?-)

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