LMP7704-SP: Part Number Confusion

Part Number: LMP7704-SP

Hello, I am looking at getting PN LMP7704-SP. When looking at what to order, I am seeing 5962R1920601VXC and LMP7704HBH/EM .. Both of these part number seem to be linked to LMP7704-SP but the first one is much more expensive. what is the difference between to two parts?? And is it possible to get quotes for each? Thank you, James Lana

Hello James,

The /EM is an engineering model.

TI Engineering Evaluation Units vs. MIL-PRF-38535 QML Class V Processing (Rev. B)

TI engineering evaluation (/EM and -MPR) models are units intended for engineering evaluation only. While using the same die
as fully qualified and processed space-grade products (QMLV or products appended with the suffix -MLS), they are processed
to a noncompliant flow (for example, no burn-in) and tested to a temperature rating of +25°C only. These units are not suitable
for qualification, production, radiation testing or flight use. Engineering models are not specified for performance over the full
military specified temperature range of –55°C to +125°C or for operating life. For more information about engineering models,
see the “TI Engineering Evaluation Units vs. MIL-PRF-38535 QML Class V Processing application report
