Analog switches, multiplexers, and demultiplexers are vital components of circuit boards. They provide the capability to selectively route signals between different node points. ADG508FBRNZ fall into the same family and is an integrated circuit containing 8 channels of switches making them ideal for applications requiring a variable amount of switchpoints. This article with discuss the application field and working principle of ADG508FBRNZ.

The ADG508FBRNZ switch IC offers 8 single-pole/single-throw (SPST) switches. The switch is of a low ON-resistance type, which makes it a perfect choice for low resistance switch applications. Additionally, its 6-V to 30-V operating voltage range makes it usable for a plethora of industrial applications. It is suitable for use in wide temperature range -40 °C to 125 °C.

ADG508FBRNZ can be used in applications such as test and measurement, automotive, communications, HVAC, instrumentation and medical fields. Test and measurement include applications such as switching systems, automated testing and data acquisition. Automotive applications include audio systems and electric window control systems. In HVAC, ADG508FBRNZ can be used in defrost and power control systems. Due to low ON-resistance measurement, the integrated switches are suitable for use in high current density applications as well as communication, instrumentation and medical fields. Moreover, the switch IC has glitch-free switching performance and low leakage current and leakage resistance.

The working principle of the ADG508FBRNZ is based on its internal logic circuits, which control the switching process for each channel. The control circuit is made up of two parts: an input logic circuit and a control circuit. The control circuit contains voltage sensitive switches that control the flow of electrical currents from one channel to another. The switches are turned on and off depending on the input logics received from the input logic circuit. The current controls a gate, which connects one or more nodes in the strip. When two or more switches are turned on, the current flows from the controlled node to the target node. This current will be diverted to the target node until the logic circuit receives a signal or a higher voltage, thus turning off the switch. This process continues until all circuits are connected. In other words, the control circuit and input logic control the switching process based on logic levels set by the user.

In sum, ADG508FBRNZ is an advanced IC switch featuring 8 channels of low ON-resistance type switches. These switches are suitable for a multitude of industrial applications because of their wide operating temperature range and 6-V to 30-V operating voltage. The switch IC has glitch-free switching performance and low leakage current and leakage resistance. The ADG508FBRNZ switches are controlled by an internal logic circuit, which contains voltage sensitive switches. The current controls a gate that links one or more nodes in the strip, and the logic circuit controls the switching process based on logic levels set by the user.
