The ADG795A/ADG795G is a monolithic CMOS device comprising five 2:1 multiplexer/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 wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range make the ADG795A/ADG795G the ideal switching solution for a wide range of TV applications including S-Video, RGB and YPbPr 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 ADG795A/ADG795G switches exhibit breakbefore- make switching action. The ADG795G has one 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 settable 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 ADG795A/ADG795G operates from a single 3V or 5V supply voltage and is available in a compact 4x4mm body, 24- lead lead free LFCSP package.
