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 ± 2.5 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 that extends to the supplies.
The ADG706 and ADG707 are available in small 28-lead TSSOP
packages.
