GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

1. 20-Lead 4 mm ϫ 4 mm Chip Scale Package (CSP).

The ADG781, ADG782, and ADG783 are monolithic CMOS

devices containing four independently selectable switches. These

switches are designed on an advanced submicron process that

provides low power dissipation and high switching speed, low on

resistance, low leakage currents and high bandwidth.

2. 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.

They are designed to operate from a single 1.8 V to 5.5 V sup-

ply, making them ideal for use in battery powered instruments

and with the new generation of DACs and ADCs from Analog

Devices. Fast switching times and high bandwidth make the

part suitable for video signal switching.

3. Very Low R_ON(4.5 Ω max at 5 V, 8 Ω max at 3 V). At supply

voltage of 1.8 V, R_ONis typically 35 Ω over the temperature

range.

4. Low On-Resistance Flatness.

5. –3 dB Bandwidth >200 MHz.

The ADG781, ADG782, and ADG783 contain four independent

single-pole/single throw (SPST) switches. The ADG781 and

ADG782 differ only in that the digital control logic is inverted.

The ADG781 switches are turned on with a logic low on the

appropriate control input, while a logic high is required to turn

on the switches of the ADG782. The ADG783 contains two

switches whose digital control logic is similar to the ADG781,

while the logic is inverted on the other two switches.

6. Low Power Dissipation. CMOS construction ensures low

power dissipation.

7. Fast t_ON/t_OFF.

8. Break-Before-Make Switching. This prevents channel shorting

when the switches are configured as a multiplexer (ADG783

only).

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.
