[FAQ] LM358LV: What is the difference between the LM358, LM358B, and LM358LV op amp replacements?

Part Number: LM358LV
Other Parts Discussed in Thread: LM358B, LM358-N, , LM358, LM324, LM321LV, LM324LV, LM321

Hello,

When searching for an LM358 I found a bunch of different versions, LM358, LM358-N, LM358B, and LM358LV.

What's the difference between all of these devices? Can you share some pros and cons between them?

Thanks,

David

    Hello David,

    Great question! First, let me point you to a dynamic link that compares these devices from a specification and cost perspective:

    Comparison of LM358 devices.

    Now, let's discuss each of these individually:

    LM358: This device was designed and released by TI back in the 1990's. It is a legacy device that has a max supply voltage of up to 32V, depending on grade. It is ubiquitous and is manufactured by many semiconductor companies (though they all have small differences that are beyond the scope of this forum post).

    LM358-N: As mentioned above, the LM358 is manufactured by multiple semiconductor companies. One of those companies, National Semiconductor, was acquired by TI back in 2011. Therefore the National Semiconductor version of the LM358 was renamed LM358-N.

    Both the LM358 and LM358-N had good performance for their target price back when they were designed. However, new design techniques, process technologies and manufacturing improvements have enabled TI to create new devices that are optimized for common applications. Furthermore, the newer devices have EMI filtering, lower power, wider temperature range, better initial input offset voltage and Vos drift, and are still budget-friendly.

    LM358LV: The "LV" means "Low Voltage", so the primary difference is supply voltage (5.5V max vs. 32V max). The "LV" version was developed because we found many customers were using the higher-voltage LM358 and LM358-N in low-voltage applications. The "LV" version is better suited for low-voltage applications (e.g. lower power, better offset and drift). Please note that the single channel LM321 and quad channel LM324 also have "LV" versions (LM321LV and LM324LV).

    LM358B: The primary difference again is supply voltage (36V max vs. 32V max). The "B" version was developed for a variety of reasons. First, many applications have +/- 15V supplies, so having a maximum supply voltage of 36V is desirable. Also, the "B" version has better performance in just about every specification including offset, gain bandwidth, slew rate, and wider temperature range. Finally, like most new devices, the "B" version has EMI filters.
