The ADG5208F switches one of eight inputs to a common output, and the ADG5209F switches one of four differential inputs to a common differential output. An EN input on both devices enables or disables the device. Each channel conducts equally well in both directions when on, and each channel has an input signal range that extends to the supplies. The digital inputs are compatible with 3 V logic inputs over the full operating supply range. When no power supplies are present, the channel remains in the off condition, and the switch inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed positive fault voltage (VDD) or negative fault voltage (VSS) by a threshold voltage (VT), the channel turns off and that Sx pin becomes high impedance. If the fault channel is selected, the drain pin is pulled to the secondary supply voltage that was exceeded. Rev.

ADG5209F Functional Block Diagram Input signal levels of up to −55 V or +55 V relative to ground are blocked, in both the powered and unpowered conditions. The low capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch switching and fast settling times are required. PRODUCT HIGHLIGHTS 1. The source pins are protected against voltages greater than the supply rails, up to −55 V and +55 V. 2. The source pins are protected against voltages between −55 V and +55 V in an unpowered state. 3. Trench isolation guards against latch-up. 4. Optimized for low charge injection and on capacitance. 5. The ADG5208F/ADG5209F can be operated from a dual supply of ±5 V up to ±22 V or a single power supply of 8 V up to 44 V. 13035-002 One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A.
