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. PRODUCT HIGHLIGHTS The ADG441, ADG442 and ADG444 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced LC2MOS process that provides low power dissipation yet gives high switching speed and low on resistance. The on res...
