GENERAL DESCRIPTION

The ADG608 and ADG609 are monolithic CMOS analog mul-

tiplexers comprising eight single channels and four differential

channels respectively, fully specified for 5 V, +5 V and +3 V

power supplies. The ADG608 switches one of eight inputs to a

common output as determined by the 3-bit binary address lines

A0, A1 and A2. The ADG609 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 de-

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

channels are switched OFF. All the address and enable inputs

are TTL compatible over the full specified operating tempera-

ture range, making the parts suitable for bus-controlled systems

such as data acquisition systems, process controls, avionics and

ATEs since the TTL compatible address inputs simplify the digital

interface design and reduce the board space requirements.

The ADG608/ADG609 are designed on an enhanced LC

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 which extends to the supplies. In the OFF condition, sig-

nal 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.

Performance Analog Multiplexers

The ability to operate from single +3 V, +5 V or 5 V bipolar

supplies makes the ADG608 and ADG609 perfect for use in

battery operated instruments and with the new generation of

DACs and ADCs from Analog Devices. The use of 5 V sup-

plies and reduced operating currents gives much lower power

dissipation than devices operating from 15 V supplies.
