GENERAL DESCRIPTION
The ADG431, ADG432 and ADG433 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 dissipa-
tion making the parts ideally suited for portable and battery
powered instruments.
The ADG431, ADG432 and ADG433 contain four indepen-
dent SPST switches. The ADG431 and ADG432 differ only in
that the digital control logic is inverted. The ADG431 switches
are turned on with a logic low on the appropriate control input,
while a logic high is required for the ADG432. The ADG433
has two switches with digital control logic similar to that of the
ADG431 while the logic is inverted on the other two switches.
Each switch conducts equally well in both directions when ON
and has an input signal range which 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 ADG431, ADG432 and ADG433 are fabricated on an
enhanced LC
2
MOS process 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 config-
ured as a multiplexer.
5. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG431, ADG432, and ADG433 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.

NOTES

Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
2
Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG431/ADG432/ADG433 features proprietary ESD protection circuitry, perma-
nent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

TRENCH ISOLATION
In the ADG431A, ADG432A and ADG433A, an insulating
oxide layer (trench) is placed between the NMOS and PMOS
transistors of each CMOS switch. Parasitic junctions, which
occur between the transistors in junction isolated switches, are
eliminated, the result being a completely latch-up proof switch.
In junction isolation, the N and P wells of the PMOS and NMOS
transistors from a diode that is reverse-biased under normal
operation. However, during overvoltage conditions, this diode
becomes forward biased. A silicon-controlled rectifier (SCR)
type circuit is formed by the two transistors causing a significant
amplification of the current which, in turn, leads to latch up.
With trench isolation, this diode is removed, the result being a
latch-up proof switch.

APPLICATION
Figure 2 illustrates a precise, fast sample-and-hold circuit.
An AD845 is used as the input buffer while the output opera-
tional amplifier is an AD711. During the track mode, SW1 is
closed and the output V
OUT
follows the input signal V
IN
. In
the hold 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 will decrease with time. The ADG431/ADG432/
ADG433 minimizes this droop due to its low leakage specifica-
tions. 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 will be at the same potential, they will have a differen-
tial effect on the op amp AD711 which will minimize charge
injection effects. Pedestal error is also reduced by the compensa-
tion network R
C
and C
C
. This compensation network also reduces
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.
