GENERAL DESCRIPTION
The ADG408/ADG409 are monolithic CMOS analog multiplexers
comprising eight single channels and four differential 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 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 the device is disabled,
all channels are switched off.
The ADG408/ADG409 are designed on an enhanced LC
2
MOS
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.
The ADG408/ADG409 are improved replacements for the
DG408/DG409 analog multiplexers.
PRODUCT HIGHLIGHTS
1. Extended Signal Range. The ADG408/ADG409 are
fabricated on an enhanced LC
2
MOS process, giving an
in
creased signal range that extends to the supply rails.
2. Low Power Dissipation.
3. Low R
ON
.
4. S
ingle-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 remain
functional with single supplies as low as 5 V.
