Hot-selling and scarce ADG729BRU Low-Voltage, 2-Wire Serially-Controlled, Matrix Switches TSSOP16 spot stock

Product Descriptions

The ADG728 and ADG729 are CMOS analog matrix switcheswith a serially controlled 2-wire interface . The ADG728 is an8-channel matrix switch, while the ADG729 is a dual 4-channelmatrix switch . On resistance is closely matched between switchesand very flat over the full signal range . These parts can operateequally well as either multiplexers, demultiplexers or switcharrays and the input signal range extends to the supplies .

The ADG728 and ADG729 utilize a 2-wire serial interface thatis compatible with the I²C™ interface standard . Both have twoexternal address pins (A0 and A1). This allows the 2 LSBs ofthe 7-bit slave address to be set by the user . Four of each of thedevices can be connected to the one bus . The ADG728 also hasa RESET pin that should be tied high if not in use .

Each channel is controlled by one bit of an 8-bit word . Thismeans that these devices may be used in a number of differentconfigurations; all, any, or none of the channels may be on atany 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 TSSOPpackages .​
