Note 3: All typicals are given for VCC = 5V and TA = 25°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 q 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.
