GENERAL DESCRIPTION
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.
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 VL pin. The ADG441 and ADG442 do not
have a VL pin, the logic power supply is generated internally by
an on-chip voltage generator.
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.
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.
2. Low power dissipation.
3. Low RON.
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.
