SWITCHES SHOWN FOR A LOGIC 1 INPUT

Figure 1.

Each switch conducts equally well in both directions when ON

and has an input signal range that extends to the power

supplies. 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 the low charge injection for minimum transients when

switching the digital inputs.

APPLICATIONS

Audio and video switching

Automatic test equipment

Precision data acquisition

Battery-powered systems

Sample-and-hold systems

Communication systems

PRODUCT HIGHLIGHTS

1. Extended signal range. The ADG441A/ADG442A/

ADG444A are fabricated on an enhanced LC²MOS,

trench-isolated process, giving an increased signal range

that extends to the supply rails.

GENERAL DESCRIPTION

2. Low power dissipation.

The ADG441, ADG442, and ADG444 are monolithic CMOS

devices that comprise of 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.

3. Low R_ON

4. Trench isolation guards against latch-up for A grade parts.

A dielectric trench separates the P and N channel

transistors thereby preventing latch-up even under severe

overvoltage conditions.

5. Break-before-make switching. This prevents channel

shorting when the switches are configured 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.

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

range, which ensures good linearity and low distortion when

switching audio signals. High switching speed also makes the

parts suitable for video signal switching. CMOS construction

ensures ultralow power dissipation, making the parts ideally

suited for portable and battery-powered instruments. The

ADG441, ADG442, and ADG444 contain four independent

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 logic high on the

appropriate control input. The ADG441 and ADG444 switches

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

that is applied to the V_Lpin. The ADG441 and ADG442 do not

have a V_Lpin, the logic power supply is generated internally by

an on-chip voltage generator.
