Hot-selling and scarce ADG781BCP 2.5Ω Quad SPST Switches QFN spot stock

Product Descriptions

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 .
