GENERAL DESCRIPTION

The ADG406, ADG407 and ADG426 are monolithic CMOS

analog multiplexers. The ADG406 and ADG426 switch one of

sixteen inputs to a common output as determined by the 4-bit

binary address lines A0, A1, A2 and A3. The ADG426 has on-

chip address and control latches that facilitate microprocessor

interfacing. The ADG407 switches one of eight differential

inputs to a common differential output as determined by the 3-

bit binary address lines A0, A1 and A2. An EN input on all

devices is used to enable or disable the device. When disabled,

all channels are switched OFF.

The ADG406/ADG407/ADG426 are designed on an enhanced

LC

high switching speed and low on resistance. These features

make the parts suitable for high speed data acquisition systems

and audio signal switching. Low power dissipation makes the

parts suitable for battery powered systems. Each channel

conducts equally well in both directions when ON and has an

input signal range which 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.

PRODUCT HIGHLIGHTS

1. Extended Signal Range

The ADG406/ADG407/ADG426 are fabricated on an

enhanced LC

which extends 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

ADG406/ADG407/ADG426 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.
