Interface - Analog Switches, Multiplexers, Demultiplexers

The DG333ALDW-E3 is a 16-channel analog multiplexer/demultiplexer, found in the product category Interface – Analog Switches, Multiplexers, Demultiplexers. It can function as both a switch and as a signal router, allowing signal access to shared resources by switching between multiple inputs. The same product can also be used as a data distributor, allowing the same signal to be sent to multiple outputs.

Application Field:

The DG333ALDW-E3 is suitable for applications associated with computers, automatic control systems, such as instrument amplifiers, analog-to-digital converters, digital-to-analog converters, and various types of interface circuits. It has excellent characteristics, such as high-speed switching speed, low power consumption, and excellent dv/dt performance which make it capable of meeting various requirements.

Working Principle:

The DG333ALDW-E3 operates by utilizing two analog inputs. The input signal is applied to two switching pins, one for the channel to be switched and the other for the channel to be switched to the multiplexer. The output is then generated by a single analog output based on the signals applied to the switching pins. The output will depend on the relationship between the input and the switching pins, allowing for accurate signal transfer.

The DG333ALDW-E3 has an on-chip control DAC and a comparator to ensure accurate control of the channel. The control DAC is used to set the switching point, with an accuracy of one-tenth of a Volt for 0.1V increments. This ensures that the analog input is always switched to the correct output when the normal operations take place.

The DG333ALDW-E3 also includes an on-board power supply, a memory block, and an oscillator which controls timing by controlling the switching frequency. In addition, the product provides the necessary isolation characteristics to prevent the multiplexer from being damaged by high voltage or other external electromagnetic interference. Furthermore, it has several protection features to protect the product against electrical and thermal damage.

The DG333ALDW-E3 is a great example of highly advanced and reliable analog switching products which make up a significant part of the Interface – Analog Switches, Multiplexers, Demultiplexers product category. These products offer a high degree of precision, excellent dv/dt performance, and low power consumption, making them ideal for a variety of applications.
