Description

The ADG411, ADG412 and ADG413 are monolithic CMOS devices comprising four independently selectable switches. ADG411, ADG412 and ADG413  are designed on an enhanced LC² MOS process which provides low power dissipation yet gives high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation making the parts ideally suited for portable and battery powered instruments.

The ADG411, ADG412 and ADG413 contain four independent SPST switches. The ADG411 and ADG412 differ only in that the digital control logic is inverted. The ADG411, ADG412 and ADG413  switches are turned on with a logic low on the appropriate control input. The ADG411, ADG412 and ADG413 have two switches with digital control logic similar to that of the products while the logic is inverted on the other two switches. Each switch conducts equally well in both directions when ON and each has an input signal range that extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All switches exhibit 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 inputs.
