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.
