Resistor Networks, Arrays

Resistor networks, or arrays, are the most common type of resistor used in electronics, due to their tremendous flexibility and variety of applications. They are commonly used to provide both resistive and capacitive effects, to create pulse shaping circuitry, and to provide low-cost solutions to impedance matching problems.

What are Resistor Networks or Arrays?

Resistor networks, or arrays, are essentially groups of resistors combined into one package. These packages can contain anywhere from two to hundreds of resistors, providing the designer with amazing flexibility. Each resistor within the network, or array, may be individually specified and/or adjusted.The most common type of resistor networks are series and parallel arrays. In a series arrangement, the resistors are connected one after the other, and the combined resistance of the array is equal to the sum of the resistors. In a parallel arrangement, the resistors are connected side by side, and the combined resistance of the array is equal to the inverse of the sum of the resistors.

77061270 Application Field

The most common uses of resistor networks are in communications, signal processing, and power supply applications. In communications, resistor networks are used to provide impedance matching between an output stage and the load, such as antennas and other receivers. They are also used to control voltage divider bias circuits, which helps maintain a constant voltage across a load. In addition, some networks are designed to create precision voltage dividers that provide very specific ratios.In signal processing, resistor networks are used to form filter networks, or bandpass filters, to create custom frequency responses. They are also used to create constant current sources, providing more precise current regulation than can be obtained with a single resistor.In power supply applications, resistor networks are used to control voltage and/or current regulators, such as linear regulators and switching regulators. They can also be used to provide voltage divider bias circuits, providing precise voltage control of power supply voltages.

77061270 Working Principle

The working principle of 77061270 resistor networks is simple. When voltage is applied to the array, the resistors divide the voltage, and the current flows through the appropriate resistors based on their resistance. For example, in a series array, a higher resistance resistor will have a larger voltage drop across it, and therefore more current will flow through it. In a parallel array, the total combined resistance of the array will be lower than the resistance of the individual resistors because of the parallelism. As a result, more current will flow through each resistor relative to a series array. In both cases, each resistor in the array is performing the same basic function of providing resistance, and the exact voltage and current distribution is determined by the resistance of the individual resistors.

Conclusion

Resistor networks, or arrays, are indispensable components of all sorts of electronic circuits, from communications to power supply, and signal processing applications. Their versatile nature and wide range of applications make them an invaluable tool for any electronic engineer. Understanding how these resistor networks work and how to use them will give any designer a powerful tool for circuit design.
