GENERAL DESCRIPTION

The ADG1308 and ADG1309 are monolithic analog multi-

plexers consisting of eight single channels and four differential

channels, respectively. The ADG1308 switches one of eight

inputs to a common output as determined by the 3-bit binary

address lines A0, A1, and A2. The ADG1309 switches one of

four differential inputs to a common differential output as

determined by the 2-bit binary address lines A0 and A1. An EN

input on both devices is used to enable or disable the device.

When disabled, all channels are switched off.

When the switches are on, each switch conducts equally well

in both directions 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.

Fast switching speed coupled with high signal bandwidth makes

the parts suitable for video signal switching. CMOS

construction ensures ultra low power dissipation, making the

parts ideally suited for portable and battery-powered

instruments.
