LOGIC "1" INPUT

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.

PRODUCT HIGHLIGHTS

1. Extended Signal Range

The ADG419 is fabricated on an enhanced LC

cess, giving an increased signal range that extends to the

supply rails.

2. Ultralow Power Dissipation

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 will remain functional with single supplies as low as

+5 V.
