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 switching 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 highswitching 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. 1. Single/Dual Supply Operation. The ADG706 and ADG707 are fully specified and guaranteed with 3 V and 5 V single supply and 3 V dual supply rails. 2. Low On Resistance (2.5 typical). 3. Low-Power Consumption (<0.01 W). 4. Guaranteed Break-Before-Make Switching Action. 5. Small 28-Lead TSSOP Package. REV. 0 Information furnished by Analog Devices is believed to be accurate and reliable.

This is a stress rating only, functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time. 2 Overvoltages at IN, S or D will be clamped by internal diodes. Current should be limited to the maximum ratings given. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG706/ADG707 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. WARNING!
