The ADG729 is a CMOS analog matrix switch with a serially controlled 2-wire interface. It is a dual 4-channel matrix switch. On resistance is closely matched between switches and very flat over the full signal range. This part can operate equally well as a multiplexer, demultiplexer or switch array and the input signal range extends to the supplies. The ADG728 and ADG729 utilize a 2-wire serial interface that is compatible with the I2C™ interface standard. Both have two external address pins (A0 and A1). This allows the 2 LSBs of the 7-bit slave address to be set by the user. Four of each of the devices can be connected to the one bus. The ADG728 also has a RESET pin that should be tied high if not in use. Each channel is controlled by one bit of an 8-bit word. This means that these devices may be used in a number of different configurations; all, any, or none of the channels may be on at any one time. On power-up of the device, all switches will be in the OFF condition and the internal shift register will contain all zeros. All channels exhibit break-before-make switching action preventing momentary shorting when switching channels. The ADG728 and ADG729 are available in 16-lead TSSOP packages.
