The ADG781, ADG782, and ADG783 are monolithic CMOSdevices containing four independently selectable switches. Theseswitches are designed on an advanced submicron process thatprovides low power dissipation and high switching speed, low onresistance, low leakage currents and high bandwidth.They are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery powered instrumentsand with the new generation of DACs and ADCs from AnalogDevices. Fast switching times and high bandwidth make thepart suitable for video signal switching.The ADG781, ADG782, and ADG783 contain four independentsingle-pole/single throw (SPST) switches. The ADG781 andADG782 differ only in that the digital control logic is inverted.The ADG781 switches are turned on with a logic low on theappropriate control input, while a logic high is required to turnon the switches of the ADG782. The ADG783 contains twoswitches whose digital control logic is similar to the ADG781,while the logic is inverted on the other two switches.Each switch conducts equally well in both directions when ON.The ADG783 exhibits break-before-make switching action.The ADG781 / ADG782 / ADG783 are available in 20-lead chipscale packages.PRODUCT HIGHLIGHTS 20-Lead 4 mm × 4 mm Chip Scale Package (CSP). 1.8 V to 5.5 V Single Supply Operation. The ADG781, ADG782, and ADG783 offer high performance and are fully specified and guaranteed with 3 V and 5 V supply rails. Very Low RON (4.5 Ω max at 5 V, 8 Ω max at 3 V). At supply voltage of 1.8 V, RON is typically 35 Ω over the temperature range. Low On-Resistance Flatness. –3 dB Bandwidth >200 MHz. Low Power Dissipation. CMOS construction ensures low power dissipation. Fast tON/tOFF. Break-Before-Make Switching. This prevents channel shorting when the switches are configured as a multiplexer (ADG783 only).APPLICATIONS Battery Powered Systems Communication Systems Sample Hold Systems Audio Signal Routing Video Switching Mechanical Reed Relay Replacement
