[FAQ] LMV358: What is the best cross reference replacements for the LMV321, LMV358, LMV324 op amp devices?

Part Number: LMV358

Hi,

Are there any good (or better) replacement op amps for the LMV3xx devices (i.e. LMV321, LMV358, LMV324)?

I'm looking for a device that can stay within my budget and has extra features like EMI/RFI filters on the inputs, better voltage offset, and lower power .

  • Hello David,

    Yes, there are some excellent drop-in replacement devices for the LMV3XX family of devices!  Please consider the LMV358A, LMV324A, LMV321A as replacements.  These new devices include everything you mentioned and have a wider supply voltage, faster slew rate, lower noise, and are more budget-friendly.  

    For a more complete comparison, please check out the following link.

  • Hi Davis,

    TI has tons of better OPAmps. Specify the desired offset voltage and supply current. Also specify the desired unity gain bandwidth. And, how many amplifiers shall the OPAmp contain?

    Hello Kai,

    Thanks for pointing out that we have many better op amps.  :) 

    However, the idea here is finding a family of devices with comparable performance for the cost of the LMV3XX devices.  The new 'A' versions have better performance and are more budget-friendly than the 'non-A' versions.  If the 'A' versions are not sufficient replacements for the application(s), we can certainly provide additional guidance on selecting different devices based on more detailed criteria like what you mentioned above.

    Hi Peter,

    I think the TLV9001, TLV9002, TLV9004 is an optimal alternative.

    Thanks Kai! Thanks Peter!

    Hello Kai,

    Those are excellent alternatives as well!

    To your point, many of the classic amplifiers such as LM3XX, LMV3XX, LM2904, LM2902, LM2904-Q1, etc. can be replaced with newer 'A', 'B', and 'LV' devices. There are also new TLV prefix devices, too.
    Here is a general guideline for replacements:

    LMV358, LMV321, LMV324->LMV358A, LMV321A, LMV324A
    LM358, LM358A->LM358B (for high-voltage applications) or LM358LV (for low-voltage applications)
    LM2904->LM2904B (for high-voltage applications), LM2904LV (for low voltage applications)
    LM2902->LM2902LV (for low voltage applications)
    LM2904-Q1->LM2904B-Q1

    Devices such as the TLV9001, TLV9002, TLV9004, TLV9061, TLV9062, TLV9064, and the OPA2990 (high voltage) also provide great alternatives to the classic LM and LMV devices.
