ADG728BRUZ-REEL7

ADG728 is a CMOS analogue matrix switch with a serially controlled 2-wire interface. This device is an 8-channel matrix switch. On resistance is closely matched between switches and very flat over the full signal range. This device 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 2LSBs of the 7bit secondary address to be set by the user. This device also has an active-low 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 this devices may be used in a number of different configurations; all, any, or none of the channels may be on at any one time. It is used in application such as data acquisition system, communication systems, relay placement, audio and video switching, automatic test equipment etc.

• Single supply operation is 2.7V to 5.5V
• On resistance is 2.5ohm typical at (VS = 0V to VDD, IS = 10mA)
• On-resistance flatness is 0.75ohm typical at (VS = 0V to VDD, IS = 10mA)
