High voltage 071
« on: June 30, 2014, 02:48:55 PM »
Hello.

It turned out that my design would need opamp with higher supply voltage. Does anybody know a replacement for tl071 which would have supply voltage like -10 to +40V? Offset capability required.

Thanks,

Does it have to be an SMD?

Hello,

Not at all. Any general package will do fine. I tried LM301, but it is not stable enough. LM318 might be also an option - might...

LM318 is the better choice so far but seems to be noisier in practice. If anyone knows +-40V operational voltage opamp equivalent to 071 I'm willing to hear about it.

What about the Linear LT1169.

Thanks, but it has no offset adjustment.
