GENERAL DESCRIPTION
The ADG796A is a monolithic CMOS device comprising six 2:1
multiplexer/demultiplexers controlled by a standard I²C serial
interface. The CMOS process provides ultralow power dissipa-
tion, 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 ADG796A the ideal switching solution for a
wide range of TV applications including S-Video, YPbPr, and
RGB video switches.
The switches conduct equally well in both directions when on. In
the off condition, signal levels up to the supplies are blocked. The
ADG796A switches exhibit break-before-make switching action.
The integrated I²C interface provides a large degree of flexibility
in the system design. It has two user adjustable I²C address pins
that allow up to four devices on the same bus. This allows the
user to expand the capability of the device by increasing the size
of the switching array.
