Trying to pick one out, but having a hard time discerning the difference in the datasheet - these parts look pretty much identical. What's the difference? which one should I go with?
The two products only differ in their final production test flow. So the difference is only in the specification for offset and sensitivity (as shown in Table1). The ADXL344 does not have any min/max spec for offset and sensitivity, only typical specs.
I'm not familiar with the beasts, but there does seem to have been a lot of cutting and pasting going on.
However, the main difference seems to be on the first page of the data sheet.
I noticed the 346 is dated earlier and refers to 'patent pending'.
Whereas these references have been removed on the 344 device.
Another oddity is the 346 actually mentions concurrent orientation detection - removed in the 344 device.
Interestingly the data seems to be more extensive in the 346 patent pending data sheet (More histograms etc.). The 344 device seems to have picked up three pages of empty notes at the end.
It could be worth checking the difference in availability.
Alright, thanks for the replies all. Seems like the 346 part is more 'mature', and more readily available, so I'll go with it for now. The packages are the same so I can always change my mind.
