GENERAL DESCRIPTION

The ADG511, ADG512 and ADG513 are monolithic CMOS

ICs containing four independently selectable analog switches.

These switches feature low, well-controlled on resistance and

wide analog signal range, making them ideal for precision

analog signal switching.

These switch arrays are fabricated using Analog Devices’

advanced linear compatible CMOS (LC

offers the additional benefits of low leakage currents, ultralow

power dissipation and low capacitance for fast switching speeds

with minimum charge injection. These features make the

ADG511, ADG512 and ADG513 the optimum choice for a

wide variety of signal switching tasks in precision analog signal

processing and data acquisition systems.

The ability to operate from single +3 V, +5 V or

±5 V bipolar

supplies make the ADG511, ADG512 and ADG513 perfect for

use in battery-operated instruments, 4–20 mA loop systems and

with the new generation of DACs and ADCs from Analog

Devices. The use of 5 V supplies and reduced operating currents

give much lower power dissipation than devices operating from

±15 V supplies.

The ADG511, ADG512 and ADG513 contain four indepen-

dent SPST switches. The ADG511 and ADG512 differ only in

that the digital control logic is inverted. The ADG511 switch is

turned on with a logic low on the appropriate control input,

while a logic high is required for the ADG512. The ADG513

contains two switches whose digital control logic is similar to

that of the ADG511 while the logic is inverted in the remaining

two switches.

PRODUCT HIGHLIGHTS

1. +5 Volt Single Supply Operation

The ADG511/ADG512/ADG513 offers high performance,

including low on resistance and wide signal range, fully

specified and guaranteed with +3 V,

±5 V as well as +5 V

supply rails.

2. Ultralow Power Dissipation

CMOS construction ensures ultralow power dissipation.

4. Break-Before-Make Switching

Switches are guaranteed to have break-before-make opera-

tion. This allows multiple outputs to be tied together for

multiplexer applications without the possibility of momentary

shorting between channels.
