GENERAL DESCRIPTION

The ADG419 is a monolithic CMOS SPDT switch. This switch

is designed on an enhanced LC

MOS 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 LC

MOS

process, giving an increased signal range that extends to

the supply rails.

2. Ultralow Power Dissipation.

3. Low R

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.
