LC2MOS
Precision Quad SPST Switches
ADG411/ADG412/ADG413
The ADG411, ADG412, and ADG413 contain four independent
SPST switches. The ADG411 and ADG412 differ only in that
the digital control logic is inverted. The ADG411 switches are
turned on with a logic low on the appropriate control input,
while a logic high is required for the ADG412. The ADG413
has two switches with digital control logic similar to that of the
ADG411 while the logic is inverted on the other two switches.
FEATURES
44 V supply maximum ratings
1ꢀ V analog signal range
Low on resistance (< 3ꢀ Ω)
Ultralow power dissipation (3ꢀ μW)
Fast switching times

ON < 17ꢀ ns
OFF < 14ꢀ ns
Each switch conducts equally well in both directions when on,
and each has an input signal range that extends to the 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.
TTL-/CMOS-compatible
Plug-in replacement for DG411/DG412/DG413
APPLICATIONS
Audio and video switching
Automatic test equipment
Precision data acquisition
Battery-powered systems
Sample-and-hold systems
Communication systems
PRODUCT HIGHLIGHTS
1. Extended signal range
The ADG411, ADG412, and ADG413 are fabricated on an
enhanced LC2MOS, giving an increased signal range which
extends fully to the supply rails.
GENERAL DESCRIPTION
The ADG411, ADG412, and ADG413 are monolithic CMOS
devices comprising four independently selectable switches.
They are designed on an enhanced LC2MOS process which
provides low power dissipation yet gives high switching speed
and low on resistance.
2. Ultralow power dissipation
3. Low RON
4. Break-before-make switching
This prevents channel shorting when the switches are
configured as a multiplexer.
The on resistance profile is very flat over the full analog input
range ensuring excellent linearity and low distortion when
switching audio signals. Fast switching speed coupled with high
signal bandwidth also make the parts suitable for video signal
switching. CMOS construction ensures ultralow power
dissipation, making the parts ideally suited for portable and
battery-powered instruments.
5. Single-supply operation
For applications where the analog signal is unipolar, the
ADG411, ADG412, and ADG413 can be operated from a
single-rail power supply. The parts are fully specified with a
single 12 V power supply and remain functional with single
supplies as low as 5 V.
