GENERAL DESCRIPTION
The ADG451/ADG452/ADG453 are monolithic CMOS
devices comprising four independently selectable switches.
They are designed on an enhanced LC
2
MOS process that
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, makes the parts suitable for video signal
switching. CMOS construction ensures ultralow power dissipa-
tion, making the parts ideally suited for portable and battery-
powered instruments.
The ADG451/ADG452/ADG453 contain four independent,
single-pole/single-throw (SPST) switches. The ADG451 and
ADG452 differ only in that the digital control logic is inverted. The
ADG451 switches are turned on with a logic low on the appropriate
control input, while a logic high is required for the ADG452.

ADG453
Figure 3. ADG453
The ADG453 has two switches with digital control logic similar
to that of the ADG451, 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.
The ADG453 exhibits 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.

PRODUCT HIGHLIGHTS
1. Low R
ON
(5 Ω maximum).
2. Ultralow Power Dissipation.
3. Extended Signal Range.
The ADG451/ADG452/ADG453 are fabricated on an enhanced
LC
2
MOS process, giving an increased signal range that fully
extends to the supply rails.
4. Break-Before-Make Switching.
This prevents channel shorting when the switches are
configured as a multiplexer (ADG453 only.)
5. Single-Supply Operation.
For applications in which the analog signal is unipolar, the
ADG451/ADG452/ADG453 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 5.0 V.
6. Dual-Supply Operation.
For applications where the analog signal is bipolar, the
ADG451/ADG452/ADG453 can be operated from a dual
power supply ranging from ±4.5 V to ±20 V.
