Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC3714E is 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: T_J is calculated from the ambient temperature T_A and power
dissipation P_D as follows:
LTC3714EG: T_J = T_A + (P_D • 130°C/W)
Note 4: The LTC3714 is tested in a feedback loop that adjusts V_FB to
achieve a specified error amplifier output voltage (I_TH).
Note 5: The LTC3714 VID DAC is tested in a feedback loop that adjusts
V_OSENSE to achieve a specified feedback voltage (V_FB = 0.6V) for each DAC
VID code.
