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: TJ is calculated from the ambient temperature TA and power

dissipation PD as follows:

LTC3714EG: TJ = TA + (PD • 130°C/W)

Note 4: The LTC3714 is tested in a feedback loop that adjusts VFB to

achieve a specified error amplifier output voltage (ITH).

Note 5: The LTC3714 VID DAC is tested in a feedback loop that adjusts

VOSENSE to achieve a specified feedback voltage (VFB = 0.6V) for each DAC

VID code.
