Extended Signal Range The ADG417 is a monolithic CMOS SPST switch. This switch 2 2 The ADG417 is fabricated on an enhanced LC MOS process, is designed on an enhanced LC MOS process that provides low giving an increased signal range that extends to the supply power dissipation yet gives high switching speed, low on resis- rails. tance and low leakage currents. 2. Ultralow Power Dissipation The on resistance profile of the ADG417 is very flat over the full analog input range ensuring excellent linearity and low 3. Low R ON distortion. The part also exhibits high switching speed and high 4. Single Supply Operation signal bandwidth. CMOS construction ensures ultralow power For applications where the analog signal is unipolar, the dissipation making the parts ideally suited for portable and ADG417 can be operated from a single rail power supply. battery powered instruments. The part is fully specified with a single +12 V power supply The ADG417 switch, which is turned ON with a logic low on and will remain functional with single supplies as low as the control input, conducts equally well in both directions when +5 V. ON and has an input signal range that extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. The ADG417 exhibits break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital input.
