Note1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC1699-80E, LTC1699-81E and LTC1699-82E are
guaranteed to meet performance specifications from 0 C to 70 C.
Specifications over the – 40 C to 85 C operating temperature range are
assured by design, characterization and correlation with statistical process
controls.
Note 3: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to device ground unless
otherwise specified.
