Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LTC1706EMS-61 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: With all five VID inputs floating, the VCC supply current is simply
the device leakage current. However, the VCC supply current will rise and
be approximately equal to the number of grounded VID input pins times
(VCC – 0.6V)/40k. (See the VID Input Characteristics section for more
details.)
Note 4: Each built-in pull-up resistor attached to the VID inputs also has a
series diode connected to VCC to allow input voltages higher than the VCC
supply without damage or clamping. (See Operation section for further
details.)
