GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
1. Extended signal range.
The ADG436 is a monolithic CMOS device comprising two
independently selectable SPDT switches. It is designed on an
LC2MOS process, which provides low power dissipation yet
gives high switching speed and low on resistance.
The ADG436 is fabricated on an enhanced LC2MOS
process, giving an increased signal range that extends to
the supply rails.
2. Low power dissipation.
The on resistance profile is very flat over the full analog input
range, ensuring good linearity and low distortion when
switching audio signals. High switching speed also makes the
part suitable for video signal switching. CMOS construction
ensures ultralow power dissipation, making the part ideally
suited for portable and battery-powered instruments.
3. Low RON
.
4. Single-supply operation.
For applications where the analog signal is unipolar, the
ADG436 can be operated from a single rail power supply.
Each switch conducts equally well in both directions when on
and has an input signal range which extends to the power
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.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as ꢂꢀꢀꢀ V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitryꢁ permanent damage may occur on devices subjected to high energy
electrostatic discharges. Thereforeꢁ proper ESD precautions are recommended to avoid performance degrada-
tion or loss of functionality.

POWER-SUPPLY SEQUENCING
APPLICATIONS INFORMATION
When using CMOS devices, care must be taken to ensure
correct power-supply sequencing. Incorrect power-supply
sequencing can result in the device being subjected to stresses
beyond those listed in the Absolute Maximum Ratings. Always
sequence VDD on first followed by VSS and the logic signals. An
external signal can then be safely presented to the source or
drain of the switch.
ADG436 SUPPLY VOLTAGES
The ADG436 can operate from a dual or single supply. VSS
should be connected to GND when operating with a single
supply. When using a dual supply, the ADG436 can also operate
with unbalanced supplies, for example VDD = 20 V and VSS
=
−5 V. The only restrictions are that VDD to GND must not exceed
30 V, VSS to GND must not drop below −30 V, and VDD to VSS
must not exceed +44 V. It is important to remember that the
ADG436 supply voltage directly affects the input signal range,
the switch on resistance and the switching times of the part. The
effects of the power supplies on these characteristics can be
clearly seen from the Typical Performance Characteristics
curves.
