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
1. 1.8 V to 5.5 V single-supply operation. The ADG701L/
ADG702L offer high performance, including low on
resistance and fast switching times. The ADG701L/
ADG702L are fully specified and guaranteed with 3 V
and 5 V supply rails.
2. Ver y low R

is typically 40 Ω over the
temperature range.
3. On resistance flatness R
