Description
General part information
ADG728 Series
The ADG728 is a CMOS analog matrix switch with a serially controlled 2-wire interface. It is an 8-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 andADG729utilize 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 aRESETpin 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.PRODUCT HIGHLIGHTS2-Wire Serial Interface.Single Supply Operation. The ADG728 and ADG729 are fully specified and guaranteed with 3 V and 5 V supply rails.Low On Resistance 2.5 Ω typical.Any configuration of switches may be on at any one time.Guaranteed Break-Before-Make Switching Action.Small 16-Lead TSSOP Package.APPLICATIONSData Acquisition SystemsCommunications SystemsRelay PlacementAudio and Video SwitchingAutomatic Test Equipment
