ADG406

LC2MOS 8-/16-Channel High Performance Analog Multiplexers

Analog Devices 

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.

ADG406/ADG407/ADG426

The ADG406/ADG407/ADG426 are designed on an enhanced

LC2MOS process that provides low power dissipation yet gives

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.
