GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG408 and ADG409 are monolithic CMOS analog
multiplexers comprising eight single channels and four differen-
tial channels respectively. The ADG408 switches one of eight
inputs to a common output as determined by the 3-bit binary
address lines A0, A1 and A2. The ADG409 switches one of four
differential inputs to a common differential output as deter-
mined 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 ADG408/ADG409 are designed on an enhanced LC

MOS
process which 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.
The ADG408/ADG409 are improved replacements for the
DG408/DG409 Analog Multiplexers.
1. Extended Signal Range
The ADG408/ADG409 are fabricated on an enhanced
LC
2
MOS process giving an increased signal range that
extends to the supply rails.
2. Low Power Dissipation
3 Low R
ON
4. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG408/ADG409 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.
