looking for opamp ic's that run off +/-24V

[pucho812]

o.k. So outside of the opa604 and it's dual channel counterpart the opa2604 I can't seem to find any opamp that runs off +/-24VDC I am sure there are others I just can't find any or know of any. Are there any outside of making  doa's?

Hi, ±22V is more common, anyway with this you can make any opamp work at this rails or even higher, just with 2 trans and 4 resistors, I've seen replace 2 resistros from output to bases with zenners but not necesary...

your like is 404. Most common for chips is +/-18VDC or 36V supply voltage

Some of the new power amp chips?

maybe but searches on both ti and analog devices yield nothing other then the opa604 and dual channel version 2604 listed above

thanks for those. You know maybe I didn't search right on the TI site, or maybe their search is broken. But cool man thanks for those. Now time to read data sheets

I still need to get doen to your warehouse apex jr.  As much as I would like to experiment need parts currently manufactured and fairly easily available.

There are multiple variants on that...

Here is a thread with 9 pages of discussion http://www.proaudiodesignforum.com/forum/php/viewtopic.php?f=6&t=289

Back in the '70s I made a simple audio amp for my sister from an opamp with some power darlington transistors in the PS leads.

Interesting.

I would recommend the HA12017.  If you can´t find one, look out for a cheap Ibanez RM-60, RM-80 or RM-100EX. The HA12017 are used there on every input channel.
