Note 1: Absolute Maximum Ratings are those values beyond which the life these specifications is determined by specific operating conditions in
of the device may be impaired.
Note 2: The 1696E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the -40°C to 125°C operating
junction temperature range are assured by design, characterization and
correlation with statistical process controls. The LTC1696I is guaranteed
from -40°C to 125°C, and the LTC1696H is guaranteed over the -40°C to
150°C operating junction temperature range. High junction temperatures
degrade operating lifetime; operating lifetime is derated for temperatures
greater than 125°C. The maximum ambient temperature consistent with
conjunction with board layout, the package thermal impedance and other
environmental factors. TJ is calculated from the ambient temperature, TA ,
and power dissipation, PD , according to the following formula:
LTC1696S6: TJ = TA + (PD • 192°C/W)
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.
Note 4: All typical numbers are given for VCC = 12V and TA = 25°C.
