GENERAL DESCRIPTION

The ADG741/ADG742 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 ADG741/ADG742 can operate from a single 1.8 V to 5.5 V

supply, making them ideal for use in battery-powered instru-

ments and with Analog Devices’ new generation of DACs and

ADCs.

As shown in the Functional Block Diagrams, with a logic input

of 1 the switch of the ADG741 is closed, while that of the

ADG742 is open. Each switch conducts equally well in both

directions when on.

The ADG741/ADG742 are available in 6-lead and 5-lead SC70

packages.
