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