ADG729BRUZ

产品概述

The ADG729BRUZ is a single-pole single-throw (SPST) 4-channel CMOS Analog Matrix Switch with a serially controlled 2-wire interface. On resistance is closely matched between switches and very flat over the full signal range. These parts can operate equally well as either multiplexers, de-multiplexers or switch arrays and the input signal range extends to the supplies. It utilizes a 2-wire serial interface that is compatible with the I²C™ interface standard. Have two external address pins (A0 and A1). Each channel is controlled by one bit of a 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.

• 2-wire serial interface
• Any configuration of switches may be on at any one time
• Guaranteed break-before-make switching action
• Dual 4-to-1 matrix switch
• Power-on reset
