GENERAL DESCRIPTION
The ADG428 and ADG429 are monolithic CMOS analog
multiplexers comprising eight single channels and four differen-
tial channels respectively. On-chip address and control latches
facilitate microprocessor interfacing. The ADG428 switches one
of eight inputs to a common output as determined by the 3-bit
binary address lines A0, A1 and A2. The ADG429 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. All the control
inputs, address and enable inputs are TTL compatible over the
full specified operating temperature range. This makes the part
suitable for bus-controlled systems such as data acquisition sys-
tems, process controls, avionics and ATEs because the TTL-
compatible address latches simplify the digital interface design
and reduce the board space required.
The ADG428/ADG429 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 mini-
mum transients when switching the digital inputs.
The ADG428/ADG429 are improved replacements for the
DG428/DG429 Analog Multiplexers.
PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG428/ADG429 are fabricated on an enhanced
LC
2
MOS process, giving an increased signal range that ex-
tends to the supply rails.
2. Low Power Dissipation
3. Low R
ON
4. Single/Dual Supply Operation
5. Single Supply Operation
For applications where the analog signal is unipolar, the
ADG428/ADG429 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.
