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 s
upply, 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
tch of the ADG701L is closed, while that of the ADG702L
swi
is open. Each switch conducts equally well in both directions
when on.
The ADG701L/ADG702L are packaged as 5-lead SOT-23,
6-lead S
OT-23, and 8-lead MSOP.
