Overview
The ADG739BRU-REEL7, produced by Analog Devices Inc., is a CMOS analog matrix switch featuring a serially-controlled 3-wire interface. This component is designed as a dual 4-channel matrix switch, making it suitable for both multiplexing and demultiplexing applications. Each switch can conduct equally well in both directions when on, and they can be configured as a switch array where any, all, or none of the switches may be closed at any time. The input signal range extends to the supply rails, and the device is available in a 16-lead TSSOP package.
