GENERAL DESCRIPTION
The ADG701L/ADG702L are monolithic CMOS SPST switches.
These switches are designed using an advanced submicron
process that provides low power dissipation, yet offers high
switching speed, low on resistance, and low leakage currents.
In addition, −3 dB bandwidths of greater than 200 MHz can
be achieved.
The ADG701L/ADG702L can operate from a single 1.8 V to
5.5 V supply, making it ideal for use in battery-powered
instruments and with the new generation of DACs and ADCs
from Analog Devices.
Figure 1 and Figure 2 show that with a logic input of 1, the
switch of the ADG701L is closed, while that of the ADG702L
is open. Each switch conducts equally well in both directions
when on.
The ADG701L/ADG702L are packaged as 5-lead SOT-23,
6-lead SOT-23, and 8-lead MSOP.
PRODUCT HIGHLIGHTS

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Overvoltages at IN, S, or D are clamped by internal diodes. Current should be
limited to the maximum ratings given.
ESD 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 this product features
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 degrada-
tion or loss of functionality.
