TERMINAL VOLTAGE OPERATING RANGE
There are also ESD protection diodes between V
RDAC terminals; therefore, the V
voltage boundary conditions (see Figure 31). Supply signals
present on Terminal A, Terminal B, and Terminal W that
exceed V

POWER-UP/POWER-DOWN SEQUENCES
Similarly, because of the ESD protection diodes, it is important
to power V
Terminal B, and Terminal W. Otherwise, the diode is forward-
biased such that V

the following order: GND, V
