GENERAL DESCRIPTION

The ADG711, ADG712, and ADG713 are monolithic CMOS

devices containing four independently selectable switches. These

switches are designed on an advanced submicron process that

provides low power dissipation yet gives high switching speed, low

on resistance, 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 instruments and

with the new generation of DACs and ADCs from Analog Devices,

Inc. Fast switching times and high bandwidth make the parts

suitable for switching USB 1.1 data signals and video signals.

The ADG711, ADG712, and ADG713 contain four independent

single-pole/single-throw (SPST) switches. The ADG711 and

ADG712 differ only in that the digital control logic is inverted. The

ADG711 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 ADG712. The ADG713 contains two switches whose digital

control logic is similar to the ADG711, while the logic is inverted

on the other two switches.

Each switch conducts equally well in both directions when On. The

ADG713 exhibits break-before-make switching action.

The ADG711/ADG712/ADG713 are available in 16-lead TSSOP

and 16-lead SOIC packages.

PRODUCT HIGHLIGHTS

1. 1.8 V to 5.5 V Single-Supply Operation.

The ADG711, ADG712, and ADG713 offer high performance

and are fully specified and guaranteed with 3 V and 5 V

supply rails.

2. Ver y L ow R

(4.5 Ω maximum at 5 V, 8 Ω maximum at 3 V).

At supply voltage of 1.8 V, R

is typically 35 Ω over the

temperature range.

3. Low On Resistance Flatness.

4. −3 dB Bandwidth >200 MHz.

5. Low Power Dissipation. CMOS construction ensures low

power dissipation.

6. Fast t

OFF

7. Break-Before-Make Switching.

This prevents channel shorting when the switches are

configured as a multiplexer (ADG713 only).

8. 16-Lead TSSOP and 16-Lead SOIC Packages.
