GENERAL DESCRIPTION
The ADG419 is a monolithic CMOS SPDT switch. This switch
is designed on an enhanced LC2MOS process that provides 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 distortion.
The part also exhibits high switching speed and high signal
bandwidth. CMOS construction ensures ultralow power
dissipation, 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.

PRODUCT HIGHLIGHTS
1. Extended Signal Range.
The ADG419 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 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.
