OPA2170: May we have suit part can direct replace MAX44248AUA?

Part Number: OPA2170
Other Parts Discussed in Thread: OPA2188, OPA2333

Hi Sir 

May we have suit part can direct replace MAX44248AUA?

Since cross reference i can't find the correct part.

but OPA2171AIDGK/OPA2170AIDGKR/OPA2197IDGKR/OPA2192IDGKR seems close MAX44248AUA function and P2P.

May you pls have suggestion? or other suggestion part?


  • Hi Bogey,

    Here is a link to our cross reference tool:

    In the search field if you just type in the competitor device name (MAX44248), you will get some recommendations. 

    MAX44248 has a Vos of 0.075mV. This is a precision amplifier. If you need more help choosing a specific part, I can loop you in with our precision amplifiers team for a better part recommendation. 

    Best Regards,

  • Hi Chen,

    The maximum offset voltage of the MAX44248 is 7.5uV and is a zero-drift amplifier. The 8 uMax package appears to have the same dimensions as TI's VSSOP package (but please verify for yourself). I recommend taking a look at our OPA2188. If you don't need a high voltage supply I recommend the OPA2333. Both of these devices are also zero-drift amplifiers similar to the MAX44248.

    If these devices do not work for you please let me know.

    Thank you,

  • Hi Chen,

    Will the devices I recommended work for your design? If not, please let me know and I will provide some other part numbers that may meet your needs.

    Thank you,
