ADG3257BRQ-REEL is a 15-channel mux/demux comprised of two 8:1 multiplexers and one 1:8 demultiplexers. It is ideal for inexpensive analogue-to-digital and digital-to-analog applications. It is designed with a low on-resistance channel-to-channel matching, and is optically isolated to provide independent channel paths.

This logic device is classified as a signal switch, multiplexer, and decoder due to its versatile ability to provide reliable signal control and manipulation. Signal switches provide non-linear electrical signal path alterations and manipulation. Multiplexers provide the selection or switching of multiple discrete signals with a single virtual signal. Decoders provide the connection of a digital signal to an equivalent output signal.

The application field of the ADG3257BRQ-REEL is most applicable when used to interface digital and analog signals, as well as transmit data. This device can be used to interface electronic devices with each other, such as digital devices producing analog signals, or analog devices producing digital signals. The ADG3257BRQ-REEL can also be used in A/D conversion and instrumentation.

The device’s working principle is based on the optical-isolated multiplexer and demultiplexer. It includes 8 channels that are connected from the 1st terminal (A1-A8) to the 2nd terminal (B1-B8), with each channel having a separate path for input and output. The device’s control signal (SEL) will activate 1 of 8 optical switches to direct the signal from the A-terminal to the B-terminal. The signal is then decoded and routed through to the 1:8 demultiplexer, and directed to 1 of 8 output channels, determined by the signal’s signal (SEL).

With its capability to control and transmit signals between electronic components, the ADG3257BRQ-REEL is an ideal device for digital-to-analog and analog-to-digital applications. This device is a signal switch, multiplexer, and decoder that proves to be an efficient, reliable, and inexpensive alternative to connecting and switching signals between digital and analog components.
