These 2. 1.8 V to 5.5 V Single Supply Operation. The ADG781, switches are designed on an advanced submicron process that ADG782, and ADG783 offer high performance and are provides low power dissipation and high switching speed, low on fully specified and guaranteed with 3 V and 5 V supply resistance, low leakage currents and high bandwidth. rails. They are designed to operate from a single 1.8 V to 5.5 V sup- 3. Very Low R (4.5 max at 5 V, 8 max at 3 V). At supply ON ply, making them ideal for use in battery powered instruments voltage of 1.8 V, R is typically 35 over the temperature ON and with the new generation of DACs and ADCs from Analog range.

The ADG781, ADG782, and ADG783 contain four independent single-pole/single throw (SPST) switches. The ADG781 and 6. Low Power Dissipation. CMOS construction ensures low ADG782 differ only in that the digital control logic is inverted. power dissipation. The ADG781 switches are turned on with a logic low on the 7.

The ADG783 contains two when the switches are configured as a multiplexer (ADG783 switches whose digital control logic is similar to the ADG781, only). 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 chip scale packages. C REV.
