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 instru-
ments 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.
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.
Very Low R
ON
(4.5
max at +5 V, 8
max at +3 V). At
supply voltage of +1.8 V, R
ON
is typically 35
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
ON
/t
OFF.
7.
Break-Before-Make Switching.
This prevents channel shorting when the switches are con-
figured as a multiplexer (ADG713 only).

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG711/ADG712/ADG713 feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.

APPLICATIONS
Figure 9 illustrates a photodetector circuit with programmable
gain. An AD820 is used as the output operational amplifier.
With the resistor values shown in the circuit, and using different
combinations of the switches, gain in the range of 2 to 16 can be
achieved.
