GENERAL DESCRIPTION
The ADG793A/ADG793G are monolithic CMOS devices comprising three 3:1 multiplexers/demultiplexers controllable via a standard I2C serial interface. The CMOS process provides ultralow power dissipation, yet gives high switching speed and low on resistance.
The on-resistance profile is very flat over the full analog input range, and the wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range, make the ADG793A/ADG793G the ideal switching solution for a wide range of TV applications, including RGB and YPbPr video switches.
