DG428DJ-E3 is an analog switch, multiplexer, and demultiplexer made by Texas Instruments. It is a single package containing two independent channels of 8-channel multiplexers and 4-channel demultiplexers. Each channel is controlled by 3-bits, allowing for either 8-channel single-ended multiplexing or four-channel differential multiplexing. This dual-channel device is ideal for analog signal routing applications, where it can be used to switch between multiple analog signals.

The working principle of the DG428DJ-E3 is based on the implementation of two independent 8-channel single-ended multiplexers and 4-channel differential multiplexers. Each of these multiplexers and demultiplexers is controlled by three logic inputs, which are used to select the desired output. Three bits select a unique output from the 8 output channels of the multiplexer, while four bits select a unique output from the four different outputs of the demultiplexer.

The typical application of the DG428DJ-E3 is in analog signal routing. By connecting the device to multiple analog signals, the 3-bit control inputs can be used to select a single output at any given time. This may be used to switch between two or more analog signals. The device can also be used in a differential configuration, allowing for two independent signals to be selected and routed in a single package. This makes the device ideal for applications such as signal conditioning, where two signals must be routed simultaneously.

The DG428DJ-E3 is a robust and reliable analog switch, multiplexer, and demultiplexer, and is well suited for a variety of applications. Its ease of use and simple control inputs allow it to be quickly and easily configured for a wide range of applications. By connecting multiple analog signals to the multiplexer and demultiplexer, the device can be used to quickly route multiple signals as needed. This can be used in signal conditioning applications, allowing for both signals to be routed simultaneously. Additionally, the device can be used to switch between multiple analog signals, making it ideal for signal routing applications.
