Note 1:
Note 2:
Note 3:
Limits over temperature are guaranteed by production test at +25°C and via correlation to worst-case temperature testing.
Minimum and maximum limits are guaranteed by design and characterization, but are not production tested.
The device has been characterized over the specified frequency range. Operation outside of this range is possible but not
guaranteed.
