GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

1. Extended Signal Range

The ADG428/ADG429 are fabricated on an enhanced

LC²MOS 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.

The ADG428/ADG429 are designed on an enhanced LC²MOS

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.
