GENERAL D ESCRIP TIO N
1. Extended Signal Range
T he ADG333A is a monolithic CMOS device comprising four
independently selectable SPDT switches. It is designed on an
LC2MOS process which provides low power dissipation yet
achieves a high switching speed and a low on resistance.
T he ADG333A is fabricated on an enhanced LC2MOS
process, giving an increased signal range which extends
to the supply rails.
2. Low Power Dissipation
3. Low RON
T he on resistance profile is very flat over the full analog input
range ensuring good linearity and low distortion when switching
audio signals. High switching speed also makes the part suitable
for video signal switching. CMOS construction ensures ultralow
power dissipation making the part ideally suited for portable,
battery powered instruments.
4. Single Supply Operation
For applications where the analog signal is unipolar,
the ADG333A can be operated from a single rail power
supply. T he part is fully specified with a single +12 V
supply.
When they are ON, each switch conducts equally well in both
directions and has an input signal range which extends to the
power supplies. In the OFF condition, signal levels up to the
supplies are blocked. All switches exhibit break-before-make
switching action for use in multiplexer applications. Inherent in
the design is low charge injection for minimum transients when
switching the digital inputs.

CAUTIO N
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG333A features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

ADG333A
AP P LICATIO NS INFO RMATIO N
AD G333A Supply Voltages
can be clearly seen from the characteristic curves in this data
sheet.
T he ADG333A can operate off a dual or signal supply. VSS
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 VDD = 20 V and VSS
= –5 V. T he only restrictions are that VDD to GND must not
exceed 30 V, VSS to GND must not drop below –30 V and VDD
to VSS must not exceed +44 V. It is important to remember that
the ADG333A supply voltage directly affects the input signal
range, the switch ON resistance and the switching times of the
part. T he effects of the power supplies on these characteristics
P ower 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. T his is
also true for the ADG333A. Always sequence VDD on first
followed by VSS and the logic signals. An external signal within
the maximum specified ratings can then be safely presented to
the source or drain of the switch
