The ADG708/ADG709 are low voltage, CMOS analog
S1B
multiplexers comprising eight single channels and four
DB
differential channels, respectively. The ADG708 switches one of

PRODUCT HIGHLIGHTS
1.8 V to 5.5 V make the ADG708/ADG709 ideal for battery- powered, portable instruments. All channels exhibit break- 1. Single-/dual-supply operation. The ADG708/ADG709 are before-make switching action preventing momentary shorting fully specified and guaranteed with 3 V and 5 V single-supply when switching channels. and ±2.5 V dual-supply rails. 2. Low RON (3 Ω typical). These switches are designed on an enhanced submicron process 3. Low power consumption (<0.01 μW). that provides low power dissipation yet gives high switching 4. Guaranteed break-before-make switching action. speed, very low on resistance, and leakage currents. 5. Small 16-lead TSSOP package. 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 equal y wel as either multiplexers or demultiplexers and have an input signal range that extends to the supplies. The ADG708/ADG709 are available in a 16-lead TSSOP.
