GENERAL DESCRIPTION

The ADG706 and ADG707 are low-voltage, CMOS analog

multiplexers comprising 16 single channels and eight differential

channels respectively. The ADG706 switches one of 16 inputs

(S1–S16) to a common output, D, as determined by the 4-bit

binary address lines A0, A1, A2, and A3. The ADG707 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 both devices is used to enable or disable the

device. When disabled, all channels are switched OFF.

Low-power consumption and operating supply range of 1.8 V to

5.5 V make the ADG706 and ADG707 ideal for battery-powered,

portable instruments. All channels exhibit break-before-make

switching action preventing momentary shorting when switch-

ing channels. These devices are also designed to operate from a

dual supply of

±3 V.

These multiplexers 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 which extends

to the supplies.

The ADG706 and ADG707 are available in small 28-lead TSSOP

packages.
