ADG333A
APPLICATIONS INFORMATION
ADG333A Supply Voltages
The ADG333A can operate off 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 oper-
ate with unbalanced supplies, for example V
= –5 V. The only restrictions are that 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

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 maximum ratings listed in the data sheet. This is
also true for the ADG333A. Always sequence V
followed by V
the maximum specified ratings can then be safely presented to
the source or drain of the switch
