(1) All voltages are measured with respect to the ground plugs.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its specified operating conditions.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(4) Internal zener diodes (6.3 to 8.5V) are connected from V+ to GND and VCC to GND. The zener at V+ can operate as a shunt regulator
and is connected to VCC via a conventional diode. Since the zener voltage equals the A/D's breakdown voltage, the diode insures that
VCC will be below breakdown when the device is powered from V+. Functionality is therefore ensured for V+ operation even though the
resultant voltage at VCC may exceed the specified Absolute Max of 6.5V. It is recommended that a resistor be used to limit the max
current into V+. (See Figure 24 in Functional Description)
(5) When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < Vor VIN > V+) the absolute value of current at that pin
should be limited to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply
boundaries with a 5 mA current limit to four.
(6) Human body model, 100 pF discharged through a 1.5 kΩ resistor.
