GENERAL DESCRIPTION
The ADG411, ADG412, and ADG413 are monolithic CMOS
devices comprising four independently selectable switches.
They are designed on an enhanced LC
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.

MOS process which
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.
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.
PRODUCT HIGHLIGHTS
1. Extended signal range
The ADG411, ADG412, and ADG413 are fabricated on an
enhanced LC
extends fully to the supply rails.
2. Ultralow power dissipation
3. Low R
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 remain functional with single
supplies as low as 5 V.

ADG411/ADG412/ADG413
APPLICATIONS
Figure 13 illustrates a precise, fast, sample-and-hold circuit. An
AD845 is used as the input buffer while the output operational
amplifier is an AD711. During the track mode, SW1 is closed
and the output V
mode, SW1 is opened and the signal is held by the hold
capacitor C
H
Due to switch and capacitor leakage, the voltage on the hold
capacitor decreases with time. The ADG411/ADG412/ADG413
minimizes this droop due to its low leakage specifications. The
droop rate is further minimized by the use of a polystyrene
hold capacitor. The droop rate for the circuit shown is typically
30 µV/µs.
A second switch, SW2, which operates in parallel with SW1, is
included in this circuit to reduce pedestal error. Since both
switches are at the same potential, they have a differential effect
on the op amp AD711, which minimizes charge injection
effects. Pedestal error is also reduced by the compensation
network R
and CC. This compensation network also reduces
C

.
the hold time glitch while optimizing the acquisition time.
Using the illustrated op amps and component values, the
pedestal error has a maximum value of 5 mV over the ±10 V
input range. Both the acquisition and settling times are 850 ns.
