GENERAL DESCRIPTION

The ADG752 is a low voltage SPDT (single pole, double throw)

switch. It is constructed using switches in a T-switch configura-

tion, which results in excellent Off Isolation while maintaining

good frequency 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 ADG752 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. Break-before-make

switching action ensures the input signals are protected against

momentary shorting when switching between channels.

The ADG752 is available in 6-lead SOT-23 and 8-lead

µSOIC

packages.
