Analog switches, multiplexers, and demultiplexers are all components with “on” and “off” states. ADG609BN is a bi-directional, single-pole-double-throw (SPDT) CMOS device specifically designed for switching, multiplexing, demultiplexing, and signal routing applications. It is suited for applications such as trigger logic, isolation, and power control. In this article, we will discuss the features and applications of the ADG609BN and explain the working principle of this device.

Features of ADG609BN

The main features of the ADG609BN are as follows:

• Bi-directional, single-pole-double-throw (SPDT) CMOS design.
• Low on-state resistance of 20Ω maximum.
• Switching speed of 10ns maximum when switching a 100pF capacitance.
• Low power consumption.
• Operating voltage range from 3V to 5.5V.
• High ESD rating of 2KV.

Application Fields for ADG609BN

The high-speed, low power consumption, and low on-state resistance of the ADG609BN makes it well-suited for applications such as:

• Signal relay applications.
• Data acquisition systems.
• Trigger logic.
• Isolation programs.
• Power control.
• Data routing.
• Interrupt logic.
• Battery backup.

The ADG609BN can also be used in medical devices, handheld digital devices, and surveillance systems.

Working Principle of the ADG609BN

The ADG609BN consists of two SPST analog switches and one SPDT analog multiplexer/demultiplexer. The two SPST analog switches are connected in series. The multiplexer/demultiplexer is connected between the two switches, allowing the signal to be routed from one switch to the other.

The ADG609BN is configured such that when a positive voltage is applied to the control pin, the first switch (input) is opened and the signal is routed through the multiplexer/demultiplexer and then through the second switch (output). This allows for the signal to be input to and then output from the device. When a negative voltage is applied to the control pin, the first switch (input) is closed and the signal is not routed from the first switch to the second switch.

The device also has a power-on reset feature which ensures that the device is in the “off” state when power is first applied in order to prevent any unwanted signals from entering the device. This feature is also useful in applications where power must be cycled in order to reset the device.

The ADG609BN is also designed to operate in a low-power environment, as the device only consumes 0.48mA of power when in the “on” state, and 0.03mA in the “off” state. This makes the device ideal for power-sensitive applications.

Conclusion

The ADG609BN is a high speed, low power, and low-resistance CMOS device specifically designed for switching, multiplexing, demultiplexing, and signal routing applications. The device is suited for applications such as trigger logic, isolation, and power control, as well as medical devices, handheld digital devices, and surveillance systems. The ADG609BN has a power-on reset feature and also operates in a low-power environment, making it an ideal device for power-sensitive applications.
