GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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–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.  
1. Single/Dual Supply Operation. The ADG708 and ADG709  
are fully specified and guaranteed with 3 V and 5 V single  
supply and ±3 V dual supply rails.  
2. Low RON (3 Typical).  
3. Low Power Consumption (<0.01 µW).  
4. Guaranteed Break-Before-Make Switching Action.  
5. Small 16-Lead TSSOP Package.  
Low power consumption and 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 switch-  
ing 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 a 16-lead TSSOP  
package.
