APPLICATIONS

Each switch conducts equally well in both directions when ON

and has an input signal range that extends to the power sup-

plies. In the OFF condition, signal levels up to the supplies are

blocked. All switches exhibit break-before-make switching action

for use in multiplexer applications. Inherent in the design is low

charge injection for minimum transients when switching the

digital inputs.

GENERAL DESCRIPTION

The ADG441, ADG442 and ADG444 are monolithic CMOS

devices comprising four independently selectable switches. They

are designed on an enhanced LC²MOS process that provides

low power dissipation yet gives high switching speed and low on

resistance.

PRODUCT HIGHLIGHTS

1. Extended Signal Range

The ADG441/ADG442/ADG444 are fabricated on an en-

hanced LC²MOS, trench-isolated process, giving an in-

creased signal range that extends to the supply rails.

The on resistance profile is very flat over the full analog input

range ensuring good linearity and low distortion when switching

audio signals. High switching speed also makes the parts suit-

able for video signal switching. CMOS construction ensures

ultralow power dissipation making the parts ideally suited for

portable and battery powered instruments.

2. Low Power Dissipation

3. Low R_ON

4. Trench Isolation Guards Against Latch Up

A dielectric trench separates the P and N channel transistors

thereby preventing latch up even under severe overvoltage

conditions.

The ADG441, ADG442 and ADG444 contain four indepen-

dent SPST switches. Each switch of the ADG441 and ADG444

turns on when a logic low is applied to the appropriate control

input. The ADG442 switches are turned on with a logic high on

the appropriate control input. The ADG441 and ADG444

switches differ in that the ADG444 requires a 5 V logic power

supply which is applied to the V_Lpin. The ADG441 and

ADG442 do not have a V_Lpin, the logic power supply being

generated internally by an on-chip voltage generator.

5. Break-Before-Make Switching

This prevents channel shorting when the switches are config-

ured as a multiplexer.

6. Single Supply Operation

For applications where the analog signal is unipolar, the

ADG441/ADG442/ADG444 can be operated from a single

rail power supply. The parts are fully specified with a single

+12 V power supply.
