GENERAL DESCRIPTION

The ADG792A/ADG792G are monolithic CMOS devices, each

comprising three 4:1 multiplexer/demultiplexers that are con-

process provides ultralow power dissipation yet delivers high

switching speed and low on resistance.

The on resistance profile is very flat over the full analog input

range, and wide bandwidth ensures excellent linearity and low

distortion. These features, combined with a wide input signal

range, make the ADG792A/ADG792G the ideal switching

solution for a wide range of TV applications, including RGB

and YPbPr video switches.

When turned on, the switches conduct equally well in both

directions. In the off condition, signal levels, up to the supplies,

are blocked. The ADG792A/ADG792G switches exhibit break-

before-make switching action. The ADG792G also has two

of flexibility in the system design. To build larger switching

many as eight devices to connect to the same bus.

The ADG792A/ADG792G operate from a single 3 V or 5 V

supply voltage and is available in a compact 4 mm × 4 mm

body, 24-lead, Pb-free, LFCSP package.
