GENERAL DESCRIPTION
The ADG419-EP is a monolithic CMOS SPDT switch. This
switch is fabricated on an enhanced LC2MOS process that
provides low power dissipation yet gives high switching speed,
low on resistance, and low leakage current.
The on resistance profile of the ADG419-EP is very flat over
the full analog input range, ensuring excellent linearity and low
distortion. The part also exhibits high switching speed and high
signal bandwidth. CMOS construction ensures ultralow power
dissipation, making the part ideally suited for portable and
battery-powered instruments.
Each switch of the ADG419-EP 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-EP exhibits break-before-make
switching action.
Full details about this enhanced product are available in the
ADG419 data sheet, which should be consulted in conjunction
with this data sheet.

PRODUCT HIGHLIGHTS
1. Extended Signal Range.
The ADG419-EP is fabricated on an enhanced LC2MOS
process, giving an increased signal range that extends to
the supply rails.
2. Ultralow Power Dissipation.
3. Low RON.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG419-EP can be operated from a single rail power supply.
The part is fully specified with a single 12 V power supply
and remains functional with single supplies as low as 5 V.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Only one maximum rating may be applied at any one time.
