The POWER DOWN pin is protected with ESD clamps,
as shown in
. Voltages beyond the power supplies
cause these diodes to conduct. The guidelines for limiting the
overload current in the input protection section should also be
followed for the
POWER DOWN pin.
POWER-DOWN OPERATION
Figure 48 shows the ADA4841-1 power-down circuitry. If the
POWER DOWN pin is left unconnected, then the base of the
input PNP transistor is pulled high through the internal pull-up
resistor to the positive supply, and the part is turned on. Pulling
the POWER DOWN pin approximately 1.7 V below the positive
supply turns the part off, reducing the supply current to
approximately 40 μA.
