GENERAL DESCRIPTION
The ADG799A/ADG799G are monolithic CMOS devices
comprising three 2 × 2 crosspoint switches controllable via a
standard I²C serial interface. The CMOS process provides
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
output pins controlled by the I²C interface that can also be used
to control other non-I²C-compatible devices such as video filters.
The integrated I²C interface provides a large degree of flexibility
in the system design. It has three user-adjustable I²C address

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.
