OP-amp IC

Hi,

I'm looking for an OP-amp IC that can work at +/-30V or more, performance about LM301 would do. Thanks for any suggestion.

Hi,
you might be lucky, but be prepared to build yourself a discrete opamp.

Depending of what you are going to do you will have various options.

First, what is your application?

Bandwidth, output current, gain?

You could try OPA551 (15V/usec +/-30V supplies)
or OPA445 (15V/usec +/- 45V supplies).

Both are still available from TI.

From quick look to National's opamp selection quide:
LH0004 +/- 45V
LM143,144 +/- 40V

Thanks for your suggestions, I think LM143 would be the right candidate. In the schematic I want to change the 7815/7915 to 7824/7924, that's higher than the supply V of LM301.
