GENERAL DESCRIPTION

The ADG701/ADG702 are monolithic CMOS SPST switches.

These switches are designed on an advanced submicron process

that provides low power dissipation yet high switching speed,

low on resistance, low leakage currents and –3 dB bandwidths of

greater than 200 MHz can be achieved.

The ADG701/ADG702 can operate from a single +1.8 V to

+5.5 V supply making it ideal for use in battery powered instru-

ments and with the new generation of DACs and ADCs from

Analog Devices.

As can be seen from the Functional Block Diagrams, with a

logic input of “1” the switch of the ADG701 is closed, while

that of the ADG702 is open. Each switch conducts equally well

in both directions when ON.

The ADG701/ADG702 are available in 6-lead SOT-23 and

8-lead

µSOIC packages.

PRODUCT HIGHLIGHTS
