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
REV. B

Precision 5 V/3 V Quad SPST Switches
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.

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.
CMOS construction ensures ultralow power dissipation.
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.
