GENERAL DESCRIPTION

The ADG1408 and ADG1409 are monolithic CMOS analog

multiplexers comprising eight single channels and four

differential channels, respectively. The ADG1408 switches one

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

binary address lines A0, A1, and A2. The ADG1409 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.

The ADG1408/ADG1409 are designed on an enhanced CMOS

process that provides low power dissipation yet gives high

switching speed and low on resistance. Each channel conducts

equally well in both directions when ON and has an input

signal range that extends to the supplies. In the OFF condition,

signal levels up to the supplies are blocked. All channels exhibit

break-before- make switching action, preventing momentary

shorting when switching channels. Inherent in the design is low

charge injection for minimum transients when switching the

digital inputs.
