GENERAL DESCRIPTION

The ADG799A/ADG799G are monolithic CMOS devices

comprising three 2 × 2 crosspoint switches controllable via a

ultralow power dissipation, yet offers 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 ADG799A/ADG799G the ideal switching

solution for a wide range of TV applications including RGB and

YPbPr video switches for picture-in picture applications.

The switches conduct equally well in both directions when on.

In the off condition, signal levels up to the supplies are blocked.

The ADG799A/ADG799G switches exhibit break-before-make

switching action. The ADG799G has two general-purpose logic

pins that allow up to eight devices on the same bus. This allows

the user to expand the capability of the device by increasing the

size of the switching array.

The ADG799A/ADG799G operate from single 3 V or 5 V supply

voltages and are available in a compact, 4 mm × 4 mm body,

24-lead, Pb-free LFCSP.
