Resistor Networks, Arrays

Resistor networks and arrays are electrical components made up of several resistors connected in a variety of configurations. They are primarily used to introduce attenuation, selectivity, terminated impedances and general signal conditioning within electronic circuits. A resistor network is simply a set of resistors, configured in such a way that they share current and perform a specific electronic function. Resistors can be arranged in a variety of ways, including: in parallel, in series, in ladder, in matrix, and in hybrid combinations of these. Parallel resistor networks consist of several resistors connected in parallel, the total resistance of the network is less than that of a single resistor with the same value as any of the individual resistors. Resistors connected in series form a series resistor network, and the total resistance of the network is equal to the sum of the individual resistors. In ladder networks, the resistors are connected in steps, either in a series or parallel configuration. Matrix resistor networks contain resistors arranged in rows and columns, forming a 4-terminal network. Hybrid resistor networks combine resistors connected in series, parallel, and matrix configurations to produce specific attenuation or termination characteristics. The most common applications of resistor networks are in controlling signal level and providing feedback. For example, a series resistor network can be used to reduce a signal\'s amplitude, while a parallel resistor network can be used to increase the signal\'s amplitude. They can also be used to provide feedback to a control circuit, by taking a portion of the output signal and using it to control the device. Resistor networks can also be used for impedance matching, allowing a device to drive a load of a different impedance without experiencing distortion or overload.Resistor networks and arrays are available in a variety of physical forms including: thin-film, thick-film, through-hole, and surface-mount. The physical form of the network depends upon its application and the amount of power it must handle. Low power systems such as signal conditioning systems commonly use small, surface-mount thin-film networks, while high-power systems such as power amplifiers commonly use bulky, through-hole thick-film networks. The most common type of resistor network is the R-2R network, a type of resistor ladder used to convert an analog voltage into a digital signal. This type of network is formed from a series of resistors connected in a ladder configuration. These networks are widely used in digital systems such as microcontrollers, digital-to-analog converters, and pulse width modulators. Resistor networks and arrays are used in a variety of industries including military, automotive, aerospace, telecommunications, and consumer electronics products. The main purpose of these networks is to control signal levels and provide accurate impedance matching. By using these networks, engineers can achieve reliable and cost-effective signal conditioning within their circuits.
