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.
