The ADG439FBRWZ, a monolithic CMOS device, is classified as a part of the Interface - Analog Switches, Multiplexers, Demultiplexers, series of Integrated Circuits (ICs). It is an edge-triggered noninverting analog switch that can be used for a variety of applications.

Function of ADG439FBRWZ

This IC consists of one on-chip analogy switch with two input ports, two control ports and one output port. The switch is controlled by applying a positive voltage on one of the two control ports. When this positive voltage is applied, the two input ports are connected to the one output port. The output port can be connected to ground, power connection or other circuitry, depending on the purpose of the switch. This IC is also capable of switching with a negative voltage of up to −1.6V, which enables the connection of a negative voltage output to a device that requires a −1.6V input.

Features of ADG439FBRWZ

• On-chip switch with two control ports
• Switching with a positive voltage of up to +5V
• Switching with a negative voltage of up −1.6V
• Break-before-make switching
• Fast switching with low confirmation delay
• Input protection with ESD protection
• Low on-resistance for driving large load
• Low power consumption of 4.2mA max.

Application of ADG439FBRWZ

The ADG439FBRWZ is mainly used in communications, computer systems, instrumentation, memory and data acquisition systems, and other embedded systems. It is frequently used as a single pole, two-throw analog switch for low voltage applications. This IC can be used in power switching applications such as power supply sequencing, DC-DC converters, etc. Other applications include multiplexers, data bus multiplexers, analog signal switching and channel routing, and analog and digital multiplexers.

Working Principle of ADG439FBRWZ

The ADG439FBRWZ works by utilizing metal-oxide semiconductor field-effect transistors (MOSFETs). A MOSFET is a three-terminal voltage-controlled device used to control the flow of current from the source to the drain. The source is connected to ground, while the drain is connected to the output port. The voltage at the gate controls the output voltage, which is either high or low. When the voltage at the gate is low, this closes the switch, and when the gate voltage is high, the switch opens. This makes the ADG439FBRWZ capable of switching both voltages, as long as the voltage does not exceed the maximum voltage limits.

Conclusion

The ADG439FBRWZ is a monolithic CMOS device that is part of the Interface - Analog Switches, Multiplexers, Demultiplexers, series of ICs. It is an edge-triggered noninverting analog switch with two control ports, two input ports, and one output port. This IC can switch with a positive voltage of up to +5V and a negative voltage of up to −1.6V. It is mainly used in communications, computer systems, instrumentation, memory and data acquisition systems, and other embedded systems. Its working principle is based on the use of MOSFETS, which allows it to switch both voltages without exceeding its maximum voltage limits.
