The ADG4612 & ADG4613 contain four independent singlepole/single-throw (SPST) switches. The ADG4612 switches areturned on with Logic 1 on the appropriate control input. TheADG4613 has two switches with digital control logic similar tothat of the ADG4612; the logic is inverted on the other twoswitches. Each switch conducts equally well in both directionswhen on and has an input signal range that extends to thesupplies. The ADG4613 exhibits break-before-make switchingaction for use in multiplexer applications.

When no power supplies are present the switch remains in theOFF condition and the switch inputs are high impedanceinputs. This ensures that no current flows that may damage theswitch. 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 V_DD by V_T 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.
