The DG406BDJ-E3 is an interface device specially designed by Intersil Corp. It belongs to the family of Analog Switches, Multiplexers, Demultiplexers. This device has many applications, a few of which are discussed below.

Applications

The DG406BDJ-E3 offers low-on-resistance and click-less multiplexing with low parts-count. It has low capacitance; this makes it suitable for multiplexing high-impedance signals. It is a high-impedance device and can be used as an analog multiplexer, demultiplexer or a switch. It offers four digital inputs, four independent signals, and two digital control signals. The two digital control signals can select any one of the four input signals. The four digital inputs are routed to the two output pins and the two digital control signals are routed to the four data input pins. The DG406BDJ-E3 is used in a variety of applications such as switching and multiplexing; it can also be used as a voltage switch. It is mainly used for switching power in electronic equipment such as multi-voiced audio amplifiers, D/A converters, oscillators and active filters.

Working Principle

The DG406BDJ-E3 works on the principle of analog switching. It switches the four digital inputs between the two output pins using two digital control signals. This device has two differential pairs of GND pairs, two sets of four data input pins, two sets of four output pins and two digital control signals. This is done by connecting the digital inputs and digital control signals to the appropriate pins, as per the input data.

The two differential GND pairs work as the two output pins of the device. When the control signals are applied, the digital inputs are switched between the two output pins. The digital control signals can be changed to switch the four digital inputs between the two output pins. This process is repeated until all the four digital inputs have been switched.

Conclusion:

The DG406BDJ-E3 is an analog switch, multiplexer, demultiplexer from Intersil Corporation. It is used for switching power in various electronic applications. This is done by switching the four digital inputs between the two output pins using two digital control signals. This device works on the principle of analog switching, and offers low-on-resistance and click-less multiplexing with low parts-count. It is suitable for multiplexing high-impedance signals, due to its low capacitance.
