The ADG784BCPZ is an 8-channel low-voltage analog multiplexer (MUX) and demultiplexer (DEMUX) designed to switch multiple input signals to a single output or select per a digital control input. It operates with a wide range of analog signals, providing high performance, low power and small size, making it ideal for portable and hand-held applications. This article provides a detailed description of the features, applications and working principle of the ADG784BCPZ, as well as its classification into the “interface - analog switches, multiplexers, demultiplexers” group.

The ADG784BCPZ analog multiplexer/demultiplexer offers an enabled/disabled status, which is programmable via the enable/disable line. It also provides fast switching times and low power consumption, and offers low Off-state leakage current, making it an ideal choice for a wide range of applications. It is suitable for driving a wide range of analog signals, including audio, video, data and clock, as well as a wide range of logic signals.

The ADG784BCPZ offers a number of features that make it suitable for a variety of applications. The 8 channel configuration offers numerous applications for analog signals such as audio/video multiplexing, switching ASK (amplitude shifted keying) signals, and multiplexing operational amplifiers or other analog signals. It features high dynamic range, up to 16V, and low distortion and switch-noise performance. In addition, it is compatible with 3- and 5-volt logic systems. Its 8-bit D-type input interface allows data to be shifted in either direction, making it ideal for data sampling applications. The device can also be controlled from an I2C or SPI interface, allowing for remote control and direct data streaming.

The ADG784BCPZ consists of four independent one-to-eight channels MUX/DEMUX with independent controls. The 8 relevant selectors are connected to the output/input choices of each channel and therefore provide the multiplex switching. All inputs of the ADG784BCPZ are TTL (Schmitt trigger) tolerant and are connected to the device in a 3-state mode so that no connection is made to the device when not in use. This allows power to be saved when the MUX/DEMUX is not needed.

The working principle of the ADG784BCPZ is quite simple. It can be controlled from a logic device, such as an I2C or SPI interface, or its input selectors can be manually switched for individual selection. When the input/output selection is made, the input signal is connected to the selected output, or the selected input is connected to the output, depending on the MUX/DEMUX mode. The control lines provide the information needed to select the correct signal, and the multiplexer/demultiplexer performs the signal switching as required. The control logic allows data to be shifted into or out of the device in both directions.

The ADG784BCPZ is an ideal choice for applications such as wireless communication systems, audio/video signal multiplexing, motor control, and data acquisition. Due to its low power consumption, small size and wide range of switching speeds, it is also suitable for power sensitive designs, portable electronic devices and hand-held applications. Its compatibility with 3- and 5-volt logic makes it an ideal choice for both consumer and professional products.

In conclusion, the ADG784BCPZ is a 8-channel low-voltage analog multiplexer (MUX) and demultiplexer (DEMUX), offering a wide range of features that make it ideal for a range of applications. It is classified into the “interface - analog switches, multiplexers, demultiplexers” group and offers the flexibility of both enabling and disabling the device, as well as fast switching times and low power consumption.
