GENERAL DESCRIPTION The ADG790 is a single-chip, CMOS switching solution that prises four SPDT switches and two 4:1 multiplexers. The internal architecture of the device provides two switching sections, a wide bandwidth section and a low distortion section. The wide bandwidth section contains three SPDT switches that exhibit low on resistance with excellent flatness and channel matching. This, bined with wide bandwidth, makes the three-SPDT-switch configuration ideal for high frequency signals, such as full speed (12 Mbps) and high speed (480 Mbps) USB signals and high resolution video signals. The low distortion section contains a single SPDT switch and two 4:1 multiplexers that exhibit very low on resistance and excellent flatness, making these switches ideal for a wide range of applications, including low distortion audio applications and low resolution video (CVBS and S-Video) applications. All switches conduct equally well in both directions when on and block signals up to the supply rails when off. A 4-wire...
