ADG739BRU-REEL

The ADG739BRU-REEL from Analog Devices is an integrated multiplexer/demultiplexer. It is a device that can be used to route different signals to and from different input and output ports. It is an example of an analog switch, multiplexer, and demultiplexer, which can be found in interface circuitry. This article will describe the applications and working principles of the ADG739BRU-REEL.

Applications

The ADG739BRU-REEL is used to route analog signals between one or more input and output ports. It has a very low input resistance, so it is suitable for switching between different analog voltages. It can also be used to multiplex up to 8 separate inputs into a single output, or to demultiplex one input into multiple outputs. It is often used for signal routing in consumer electronics, such as televisions, audio amplifiers, and video game consoles. It is also suitable for use in precision communication equipment and industrial control systems.

Working Principle

The ADG739BRU-REEL is a four-channel device, with a single input and four outputs. It operates by internally connecting the input to one of the outputs, depending on the control signals. There are two control inputs, S0 and S1, which select the output to be connected to the input. The device also has an enable input, EN, which can be used to enable or disable the device. When the EN input is low, the device is disabled and no signal is passed between the input and the outputs. When the EN input is high, the device is enabled and the output is selected based on the values of the S0 and S1 control inputs.

The ADG739BRU-REEL is capable of passing signals up to 15V and handling currents up to 30mA. It can be used in parallel with other devices, to increase the number of outputs or inputs. It is also suitable for use with very low quiescent currents, making it ideal for portable systems where power consumption is a concern.

Conclusion

The ADG739BRU-REEL is an integrated multiplexer/demultiplexer which can be used to route analog signals between one or more input and output ports. It is suitable for use in consumer electronics, precision communication equipment and industrial control systems. It has low power consumption, and can be used in parallel with other devices to increase the number of inputs and outputs.
