Overview
The ADG739BRU-REEL is a CMOS analog matrix switch produced by Analog Devices Inc. This component is a dual 4-channel matrix switch, designed with a serially-controlled 3-wire interface compatible with SPI, QSPI, MICROWIRE, and some DSP interface standards. The ADG739 is well-suited for both multiplexing and demultiplexing applications due to its bidirectional switch conductivity and break-before-make switching action, which prevents momentary shorting when switching channels.
