Part Number: LM1558

Tool/software:

Dear TI support,

I am looking for newer parts in TI portfolio to replace the following amplifiers parts: LM101AH, LM108AH, LM1558H. Main contraints are a power supply of +/-15V and an operating temperature within -55 degC up to 125 degC. Which parts would you recommend that are widely used now? I would need to have a SMD case and also the possibility to have a solution with one amplifier in a case or two amplifiers in a case.

Thanks in advance for your support.

Best regards,

Fabrice

Hey Fabrice,

https://www.ti.com/amplifier-circuit/op-amps/general-purpose/products.html#1192=-55%3B125&1261max=30%3B45&

Please find the above parametric search with your supply range and operating temperature. Now, LM108AH will have lower max offset, so you may need to look in TI's precision amplifiers portfolio to find a lower offset device, but the OPA4991-EP should outperform LM101 and LM1558.

Best,
Jerry

Dear Jerry,

Thanks a lot for your quick reply as well as your suggestion. Would you have a proposal for a package with only one AOP as well as a package with two AOP's?

Thanks in advance.

Best regards,

Fabrice

Hello Fabrice,

You can modify the search at the above link by changing the filters at the top of the table, please see below for an example!

There is a filter for channel counts, however we do not have any recent developments in the 1 and 2 channel per package devices.

Best,
Jerry
