Hi Sir

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

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

Hi Bogey,

Here is a link to our cross reference tool: http://www.ti.com/amplifier-circuit/op-amps/cross-reference.html.

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,

Bala Ravi

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,

Tim Claycomb
