APPLICATION INFORMATION
ADG333A SUPPLY VOLTAGES
The ADG333A can operate from a dual or signal supply. V
should be connected to GND when operating with a single
supply. When using a dual supply, the ADG333A can also
operate with unbalanced supplies; for example V
V
exceed 30 V, V
to V
the ADG333A supply voltage directly affects the input signal
range, the switch on resistance and the switching times of the
part. The effects of the power supplies on these characteristics
can be clearly seen from the Typical Performance Characteristics
curves.

POWER SUPPLY SEQUENCING
When using CMOS devices, care must be taken to ensure
correct power-supply sequencing. Incorrect power-supply
sequencing can result in the device being subjected to stresses
beyond those listed in the Absolute Maximum Ratings. This is
also true for the ADG333A. Always turn on V

or drain of the switch
