DG407BDW Application Field And Working Principle

DG407BDW is an integrated Analog Switches, Multiplexers and Demultiplexers. It is an analog and mixed-signal integrated circuit that works on single-ended input and output signals, capable of controlling the connection between two analog signal evices. This integrated circuit is available in the 8-lead plastic DIP housing with the “BDW” suffix and the 8-lead SOIC housing with the DG407BDW prefix. The DG407BDW is designed and tested to work with a wide operating temperature range of -40 to 85 degrees Celsius, while being capable of operating on a single supply voltage between 2.7 and 5.5 volts.

Application Field

The DG407BDW is primarily used in applications such as data acquisition systems, sample-and-hold systems, and instrumentation systems. Interest users can also use the DG407BDW in other specific applications, such as high-speed video, switching matrixes and low-voltage control systems. It also supports RC control of a multiplexed analog signal, and implement a switch with a very low in-channel crosstalk as well as low power consumption.

Working Principle

The DG407BDW works by providing a pair of inbalanced differential inputs (IN1 and IN2). The logic applied to the SEL1 and SEL2 inputs selects the desired channel. IN1 and IN2 are connected together to form the output (OUT). The pulse width period on SEL1 and SEL2 must exceed the propagation delay (tPD) of the device.

In its intended applications, the DG407BDW acts as sophisticated electronic control switches. For example, in a multiplexer application, the DG407BDW is capable of switching through multiplexed circuits in either one or two directions. In a demultiplexer, the DG407BDW is used to reverse the action of multiplexing circuit connection. The DG407BDW can also be used to act as a general-purpose analog such in data acquisition systems and radio frequency systems.

Conclusion

DG407BDW is an integrated analog switch, multiplexer, and demultiplexer that can be used for a variety of applications. It is designed to operate with a wide temperature range and supports single supply voltage. The DG407BDW works by providing an inbalanced differential input that allows users to select the desired channel. It acts as a sophisticated electronic control switch for multiplexer and demultiplexer applications, as well as for general-purpose analog switching systems.
