ADG799A and ADG799G APPLICATIONS RGB/YPbPr video switches HDTV Projection TV DVD-R/RW AV receivers GENERAL DESCRIPTION The ADG799A/ADG799G are monolithic CMOS devices comprising three 2 × 2 crosspoint switches 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 ADG799A/ADG799G the ideal switching solution for a wide range of TV applications including RGB and YPbPr video switches for picture-in picture applications.
The switches conduct equally well in both directions when on.
In the off condition, signal levels up to the supplies are blocked.
The ADG799A/ADG799G switches exhibit break-before-make switching action.
The ADG799G has two general-purpose logic output pins controlled by the I2C interface that can also be used to co...
