    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.)

    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.
     
  3. 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.

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

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

    George H. (I'm clueless most of the time.)
     
  7. 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.

  8. 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?
