C.
Note 4:
The LTC1487 is not tested and is not quality-assurance sampled at
–40
°
C and at 85
°
C. These specifications are guaranteed by design,
correlation, and/or inference from 0
°
C, 25
°
C and/or 70
°
C tests.
The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute maximum ratings are those beyond which the safety of
the device cannot be guaranteed.
Note 2:
All currents into device pins are positive; all currents out ot device
pins are negative. All voltages are referenced to device ground unless
otherwise specified.
