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. conjunction with board layout, the package thermal impedance and other
Note 2:
The 1696E is guaranteed to meet performance specifications environmental factors. TJ is calculated from the ambient temperature, TA , from 0°C to 85°C. Specifications over the -40°C to 125°C operating and power dissipation, PD , according to the following formula: junction temperature range are assured by design, characterization and LTC1696S6: TJ = TA + (PD • 192°C/W) correlation with statistical process controls. The LTC1696I is guaranteed
Note 3:
All currents into device pins are positive; all currents out of device from -40°C to 125°C, and the LTC1696H is guaranteed over the -40°C to pins are negative. All voltages are referenced to device ground unless 150°C operating junction temperature range. High junction temperatures otherwise specified. degrade operating lifetime; operating lifetime is derated for temperatures
Note 4:
All typical numbers are given for V greater than 125°C. The maximum ambient temperature consistent with CC = 12V and TA = 25°C. 1696fb For more information www.linear.com/LTC1696 3
