GENERAL DESCRIPTION

SWITCHES SHOWN FOR A LOGIC "1" INPUT

The ADG431, ADG432 and ADG433 are monolithic CMOS

devices comprising four independently selectable switches. They

are designed on an enhanced LC²MOS process which provides

low power dissipation yet gives high switching speed and low on

resistance.

PRODUCT HIGHLIGHTS

1. Extended Signal Range

The ADG431, ADG432 and ADG433 are fabricated on an

enhanced LC²MOS process giving an increased signal range

which extends fully to the supply rails.

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

range ensuring excellent linearity and low distortion when

switching audio signals. Fast switching speed coupled with high

signal bandwidth also make the parts suitable for video signal

switching. CMOS construction ensures ultralow power dissipa-

tion making the parts ideally suited for portable and battery

powered instruments.

2. Ultralow Power Dissipation

3. Low R_ON

4. Break-Before-Make Switching

This prevents channel shorting when the switches are config-

ured as a multiplexer.

The ADG431, ADG432 and ADG433 contain four indepen-

dent SPST switches. The ADG431 and ADG432 differ only in

that the digital control logic is inverted. The ADG431 switches

are turned on with a logic low on the appropriate control input,

while a logic high is required for the ADG432. The ADG433

has two switches with digital control logic similar to that of the

ADG431 while the logic is inverted on the other two switches.

5. Single Supply Operation

For applications where the analog signal is unipolar, the

ADG431, ADG432 and ADG433 can be operated from a

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

single +12 V power supply and will remain functional with

single supplies as low as +5 V.

Each switch conducts equally well in both directions when ON

and has an input signal range which extends to the 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 low charge

injection for minimum transients when switching the digital inputs.
