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.
