SWITCHES SHOWN FOR A “1” LOGIC INPUT
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.
