ADG444ABRZ-REEL Analog Switches, Multiplexers, and Demultiplexers

Analog switches, multiplexers, and demultiplexers are important components in many electronic circuits, as they provide a switchable connection between two or more signals. The ADG444ABRZ-REEL, manufactured by Analog Devices, is a quad single-pole/double-throw (SPDT) analog switch and multiplexer/demultiplexer, which offer 10dB on-channel isolation, low off-channel leakage, and low THD.

Application Fields

The ADG444ABRZ-REEL provides a multiplexing and routing function in a wide range of applications. It is often used in applications where multiple sources, such as sensors and other analog signals, must be switched and routed in a circuit. Some examples include instrumentation and test systems, industrial control systems, audio/video applications, optical networks, electronic security systems, and more. The device can also be used as a front-end for audio processing systems, such as mixers and samplers.

Device Specifications

The ADG444ABRZ-REEL is a quad single-pole/double-throw (SPDT) analog switch that offers 10dB on-channel isolation, low off-channel leakage and low THD. It is designed to operate on a single +5V power supply, and can switch multiplexer/demultiplexer signals up to 5Vp-p. The device features a bandwidth of 15MHz, and a throughput of 250nsec. It also has a logic logic low (Logic 0) state-on impedance of 10hms and a logic high (Logic 1) state-off impedance of only 1ohm.

Working Principle

The ADG444ABRZ-REEL uses a special switching design that allows multiple channels to be switched and routed simultaneously. A control signal is typically sent to the device, which then switches between the desired channels. The control signal can be an analog signal, such as an audio signal, or a digital signal, such as a logic signal from a microcontroller. The device has four SPDT switches, each with a single common port, one normal port and one switched port. The common port is connected to a control signal wire, and the two switched ports can be connected to input and output wires, as well as multiplexer/demultiplexer signals. The device operates by transferring a control signal to one of the switched ports, allowing the desired channel to be routed to that port.

Conclusion

The ADG444ABRZ-REEL is an efficient and versatile solution for routing and multiplexing signals in a wide range of applications. Its excellent on-channel isolation and low off-channel leakage makes it a reliable and effective routing device. Furthermore, its simple design and straightforward operating principle make it easy to use, even if you do not have a lot of experience working with analog switches, multiplexers, and demultiplexers.
