APPLICATIONS  
Each switch conducts equally well in both directions when ON  
and has an input signal range that extends to the power sup-  
plies. 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.

GENERAL DESCRIPTION  
The ADG441, ADG442 and ADG444 are monolithic CMOS  
devices comprising four independently selectable switches. They  
are designed on an enhanced LC2MOS process that provides  
low power dissipation yet gives high switching speed and low on  
resistance.  
PRODUCT HIGHLIGHTS  
1. Extended Signal Range  
The ADG441/ADG442/ADG444 are fabricated on an en-  
hanced LC2MOS, trench-isolated process, giving an in-  
creased signal range that extends to the supply rails.  
The 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 parts suit-  
able for video signal switching. CMOS construction ensures  
ultralow power dissipation making the parts ideally suited for  
portable and battery powered instruments.  
2. Low Power Dissipation  
3. Low RON  
4. Trench Isolation Guards Against Latch Up  
A dielectric trench separates the P and N channel transistors  
thereby preventing latch up even under severe overvoltage  
conditions.  
The ADG441, ADG442 and ADG444 contain four indepen-  
dent SPST switches. Each switch of the ADG441 and ADG444  
turns on when a logic low is applied to the appropriate control  
input. The ADG442 switches are turned on with a logic high on  
the appropriate control input. The ADG441 and ADG444  
switches differ in that the ADG444 requires a 5 V logic power  
supply which is applied to the VL pin. The ADG441 and  
ADG442 do not have a VL pin, the logic power supply being  
generated internally by an on-chip voltage generator.  
5. Break-Before-Make Switching  
This prevents channel shorting when the switches are config-  
ured as a multiplexer.  
6. Single Supply Operation  
For applications where the analog signal is unipolar, the  
ADG441/ADG442/ADG444 can be operated from a single  
rail power supply. The parts are fully specified with a single  
+12 V power supply.
