ADG791ABCPZ-500RL7: I²C®-Compatible, Wide BW, 4-Channel SPDT Switch
The ADG791A/ADG791G is a monolithic CMOS device comprising four 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 ADG791A/ADG791G 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 ADG791A/ADG791G switches exhibit breakbefore- make switching action. The ADG791G has one generalpurpose 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 ADG791A/ADG71G operates from a single 3 V or 5 V supply voltage and is available in a compact 4 mm × 4 mm body, 24-lead LFCSP package.
