The ADG796A is a monolithic CMOS device comprising six 2:1 multiplexer/demultiplexers 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 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.

The ADG796A operates from a single 3 V or 5 V supply voltage and is available in a compact 4 mm × 4 mm body, 24-lead, leadfree LFCSP.
