LM7171QML-SP: LM7171NABEM what is the difference with LM7171/QML/QML-SP

The LM7171 (OPN: LM7171BIN/NOPB) has a commercial temperature rating.

The LM7171QML (OPN: LM7171AMJ-QML) has a military temperature range and qualifications.

The LM7171QML-SP is space rated (for vacuum and radiation); the OPN LM7171AMJFQMLV has military qualifications, the OPN LM7171NAB/EM does not.

The 5962xxx OPNs are the same as the -J devices.

Hello Nomura-san,

I will add some context too:

Our devices with 'ML' have a military rating; this rating is most often associated with an extended temperature range and quality/reliability data on vibration testing and mean-time-between failures (MTBF).  All of our devices have quality/reliability/packaging information located at the right edge of the orderable part number 'row' on the "Ordering and Quality Information" section of the product page.

Our "SP" devices have been tested to provide a level of radiation tolerance, whether total ionizing dose (TID), single event effects (SEE), or single event latch-up (SEL) results.  This testing provides assurance to space (and other market) customers who require radiation test results.

Our "EM" or engineering model devices are non-radiation tested ICs built in the same package style as our "SP" parts.  This helps with early design, PCB layout, and other test considerations before a customer purchases the radiation-qualified device.

Electrically the devices have very similar specifications; the goal is to provide LM7171 capability across different market needs.  You may notice changes to slew rate, DC specifications, and package-related information.  For example, the thermal characteristics table will show differences across package type: some devices have enhanced plastic packages while others have ceramic packages.

Overall, if you have a key spec you are concerned about, I can help resolve any questions you may have.

We are glad to know you are considering LM7171 for a customer circuit; please let me know if you want email support from our applications team to support this business.

Best,

Alec
