GENERAL DESCRIPTION
The ADG728 and ADG729 are CMOS analog matrix switches with a serially controlled 2-wire interface. The ADG728 is an 8-channel matrix switch, while the ADG729 is a dual 4-channel matrix switch. On resistance is closely matched between switches and very flat over the full signal range. These parts can operate equally well as either multiplexers, demultiplexers or switch arrays and the input signal range extends to the supplies.
