GENERAL DESCRIPTION The ADG790 is a single-chip, CMOS switching solution that comprises 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, combined with wide bandwidth, makes the three-SPDT-switch configuration ideal for high frequency signals, such as full speed (12 Mbps) and...
