TI a new equivalents of LF357?

Hi Mokhtar, 

Welcome to E2E! 

Which package do you need the alternative for?

As Clemens mentioned, the TLE2071A is a drop-in replacement with the same balance pin functionality. We also have the TLE2081 that is the similar family as well. 

Please let me know if you have any questions.
Thank you!

Best Regards,
Ashley

thank you very much for this helpful answer 

thank you for this helpful answer; I want to use it as an opamp and as I know LF357 is sensitive to the input as I know the LF357 it's best for sensitivity input because LF357 detects and amplifies very small changes, the LF357 was doing This quite well but now it is not manufactured anymore.

I went the same replacement of this LF357n or better 

Hi Mokhtar, 

Are you referring to the PDIP-8 package version (through-hole) of the LF357? Are you specifically looking for a pin-to-pin replacement for the PDIP version or open to moving to a different surface mount package? 

Thanks!
Best Regards,
Ashley

hi 

thank you very much for your replay, I want a pin-to-pin replacement for the PDIP version, replaced with the same characteristics or better than LF357

Hi Mokhtar, 

Could you help to explain which specifications are the most important for the application? (i.e. bandwidth, noise, offset voltage, etc)

There are limited options for PDIP-8 that are more recent op amps and I could not find one that matches all the characteristics for the LF357, so it will be helpful to understand what the key careabouts are.

Thank you!
Best Regards,
Ashley
