PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG411, ADG412 and ADG413 are fabricated on an
enhanced LC
2
MOS, giving an increased signal range which
extends fully to the supply rails.
2. Ultralow Power Dissipation
3. Low R
ON
4. Break-Before-Make Switching
This prevents channel shorting when the switches are
configured as a multiplexer.
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 will remain functional with
single supplies as low as +5 V.
GENERAL DESCRIPTION
The ADG411, ADG412 and ADG413 are monolithic CMOS
devices comprising four independently selectable switches. They
are designed on an enhanced LC
2
MOS process which provides
low power dissipation yet gives high switching speed and low on
resistance.
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.
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.
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.
