GENERAL DESCRIPTION

The ADG751 is a low voltage SPST (single pole, single throw)

switch. It is constructed in a T-switch configuration, which

results in excellent Off Isolation while maintaining good fre-

quency response in the ON condition.

High off isolation and wide signal bandwidth make this part

suitable for switching RF and video signals. Low power con-

sumption and operating supply range of +1.8 V to +5.5 V make

it ideal for battery powered, portable instruments.

The ADG751 is designed on a submicron process that provides

low power dissipation yet gives high switching speed and low on

resistance. This part is a fully bidirectional switch and can handle

signals up to and including the supply rails.

The ADG751 is available in 6-lead SOT-23 and 8-lead

µSOIC

packages.
