GENERAL DESCRIPTION

The ADG708 and ADG709 are low voltage, CMOS analog

multiplexers comprising eight single channels and four

differential channels, respectively. The ADG708 switches one of

eight inputs (S1 to S8) to a common output, D, as determined

by the 3-bit binary address lines A0, A1, and A2. The ADG709

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.

Low power consumption and an operating supply range of

1.8 V to 5.5 V make the ADG708 and ADG709 ideal for

battery-powered, portable instruments. All channels exhibit

break-before-make switching action preventing momentary

shorting when switching channels.

These switches are designed on an enhanced submicron process

that provides low power dissipation yet gives high switching

speed, very low on resistance, and leakage currents.

On resistance is in the region of a few ohms and is closely

matched between switches and very flat over the full signal

range. These parts can operate equally well as either multiplexers

or demultiplexers and have an input signal range that extends to

the supplies.

The ADG708 and ADG709 are available in 16-lead TSSOP

packages.

PRODUCT HIGHLIGHTS

Single-/dual-supply operation. The ADG708 and ADG709

are fully specified and guaranteed with 3 V and 5 V single

supply and ±2.5 V dual-supply rails.

Low R

Low power consumption (<0.01 μW).

Guaranteed break-before-make switching action.

Small 16-lead TSSOP package.
