1. DESCRIPTION

The ADG441, ADG442, and ADG444BRZ-REEL are monolithic CMOS devices that comprise of four independently selectable switches. They 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, which ensures 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 ADG444BRZ-REEL contain four independent SPST switches. Each switch of the ADG441 and ADG444BRZ-REEL turns on when a logic low is applied to the appropriate control input. The ADG442 switches are turned on with logic high on the appropriate control input. The ADG441 and ADG444BRZ-REEL switches differ in that the ADG444BRZ-REEL requires a 5 V logic power supply that is applied to the VL pin. The ADG441 and ADG442 do not have a VL pin, the logic power supply is generated internally by an on-chip voltage generator.  Each switch conducts equally well in both directions when ON and has an input signal range that extends to the power 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 the low charge injection for minimum transients when switching the digital inputs.
