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.
