This is very useful in application where analog signalsmay be present at the switch inputs before power or where theuser has no control over the Power Supply Sequence.In the off condition, signal levels up to 16V are blocked. Also, ifthe analog input signal levels exceed VDD by VT then the switchwill turn off.The ultralow on resistance of these switches make them idealsolutions for data acquisition and gain switching applicationswhere low on resistance and distortion is critical. The onresistance profile is very flat over the full analog input rangeensuring excellent linearity and low distortion when switchingaudio signals.APPLICATIONS Hot swap applications Data acquisition systems Battery-powered systems Automatic test equipment Communication systems Relay ReplacementPRODUCT HIGHLIGHTS Power-Off Protection On Both S and D Pins.
