Description

The ADG441, ADG442 and ADG444 are monolithic CMOS devices comprising four independently selectable switches. ADG441, ADG442 and ADG444  are designed on an enhanced LC2
MOS process that 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 good linearity and low distortion when switching audio signals. High switching speed also makes 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 ADG441, ADG442 and ADG444 contain four independent SPST switches.  Each switch of the ADG441, ADG442 and ADG444 turns on when a logic low is applied to the appropriate control input. The ADG442 switches are turned on with a logic high on the appropriate control input.  The products switches differ in that the ADG444 requires a 5 V logic power supply which is applied to the VL pin.  The products do not have a VL pin, the logic power supply being generated internally by an on-chip voltage generator.
