GENERAL DESCRIPTION
The ADG419 is a monolithic CMOS SPDT switch. This
switch is designed on an enhanced LC
vides low power dissipation yet gives high switching speed, low
on resistance and low leakage currents.
The on resistance profile of the ADG419 is very flat over the full
analog input range, ensuring excellent linearity and low distor-
tion. The part also exhibits high switching speed and high signal
bandwidth. CMOS construction ensures ultralow power dissipa-
tion, making the parts ideally suited for portable and battery
powered instruments.
Each switch of the ADG419 conducts equally well in both
directions when ON and has an input signal range that extends
to the supplies. In the OFF condition, signal levels up to the
supplies are blocked. The ADG419 exhibits break-before-
make switching action.

The ADG419 is fabricated on an enhanced LC
cess, giving an increased signal range that extends to the
supply rails.
For applications where the analog signal is unipolar, the
ADG419 can be operated from a single rail power supply.
The part is fully specified with a single +12 V power supply
and will remain functional with single supplies as low as
+5 V.

... 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 ADG419 features proprietary ESD protection circuitry, permanent 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 ...
