Analog switches, multiplexers and demultiplexers are essential components used in modern electronic circuits. ADG528FBPZ is a CMOS analog multiplexer/demultiplexer IC from Analog Devices. This device acts as a switch that can connect one of its several input lines to its single output line, or it can work in the reverse direction, connecting one input line to multiple outputs. This application note discusses the application fields, working principle, specifications and features of the ADG528FBPZ.

The ADG528FBPZ, a 16-channel CMOS analog multiplexer/demultiplexer, can be used in many applications. It offers high-speed performance and low power consumption. It can be used in high-resolution data conversion systems, data communication systems, sensor switching applications (including low current sensor switching), scan based system testing/diagnostic applications and video routing matrix systems. It is also used in medical, automotive and industrial data acquisition, control and switching applications. It has a wide operating supply voltage range of 2.7V to 12V with a maximum toggle frequency of up to 20MHz.

The working principle of the device is fairly simple. It uses several input channels and a single output channel, and it can either connect one of its input channels to the output channel or connect one input channel to multiple output channels, depending on the configuration. It uses an input select control voltage to choose the appropriate input/output channel, and the data flow is controlled by the digital control signals sent from the system controller. The device incorporates multiple channel pass gates. When the control voltage is low, the channel is off and no data can be passed through it. When the control voltage is high, the channel is enabled and data can be passed through it.

The ADG528FBPZ has several specifications and features that make it an ideal choice for many applications. It features a low transition time of 18ns, a low input current of 0.4nA, and a low on-state resistance of 10 ohms providing ultra-low power dissipation. It also has an wide operating supply voltage range from 2.7V to 12V with up to 20MHz of toggle frequency, making it suitable for high frequency applications. It has a maximum quiescent current of 5uA and a maximum surface mount package power dissipation of 1.2W.

In conclusion, the ADG528FBPZ is a highly versatile multiplexer/demultiplexer IC that can be used in a variety of applications. It features low power consumption and can provide high speed performance. Its wide operating supply voltage range, low transition time and low on-state resistance make it an ideal choice for many applications. It is a cost-effective solution for modern electronic circuits.
