ADG408BRU-REEL

Interface - Analog Switches, Multiplexers, Demultiplexers

The ADG408BRU-REEL is an application field and working principle of an 8-channel analog switch which has both single-pole double-throw (SPDT) and double-pole double-throw (DPDT) operation. The SPDT operation allows the user to switch a single input to one of two outputs while the DPDT operation allows two independent inputs to switch the same output. This type of device is part of a family of devices called multiplexers, demultiplexers, and analog switches. All are related in their functionality to switch or multiplex signals.

Working Principle

The ADG408BRU-REEL is composed of eight, independent, single-pole double-throw (SPDT) switches which are controlled by a single control line. Each switch is comprised of two MOSFETs in antiparallel arrangement and when a voltage, either high or low, is applied to the control line the switches provide either an open or a closed path for the controlled signal. This type of multiplexer offers high switching performance in both low-current and high-current applications.

Applications

Multiplexers, demultiplexers, and analog switches like the ADG408BRU-REEL are typically used to route signals from one input to multiple outputs. They are often used in audio applications, such as mixers, as well as video applications like cameras and television sets. Multiplexers, demultiplexers, and analog switches are also used in low-power applications where the signal to be switched has low amplitude and low frequency. Other applications include automotive and telecommunications where the control of large signals is needed.

Conclusion

The ADG408BRU-REEL is a 8-channel analog switch which is part of the larger family of multiplexers, demultiplexers, and analog switches. Its SPDT and DPDT operations allow for switching a single input to one or two outputs, or two independent inputs to one output, respectively. This type of switch is used to control large signals in a variety of applications ranging from audio and video to telecommunications and automotive applications.
