<div class="Resistor"><h2>Resistor Networks, Arrays</h2><p>The 4308H-101-224LF is a resistor network device with two, four, or eight independent, isolated resistors within a single package. As part of a resistor network specifically, it is designed for the purpose of providing a low-cost "building-block" approach to circuit-board design. This specific component is designed for applications which require tight matching between resistors, such as audio frequency applications. Additionally, it is suitable for sample-and-hold circuitry, frequency-response shaping, and filtering of high frequency signals.</p><h3>Application Field</h3><p>A resistor network is useful in more circuit applications than just audio-frequency applications. The 4308H-101-224LF, for example, can be used for applications such as in low-noise amplifier designs, multiplexers, and instrumentation circuits. With its tight-matching resistors, even low-level signals can be amplified safely without distortion.</p><p>Other applications for the 4308H-101-224LF include power switching circuits and rail-to-rail (logic) level shifters. In addition to digital-to-analog converters, its four-resistor package can be used in voltage regulators and sample-and-hold circuits. As the components\' resistors are tightly matched, a certain level of control over voltage and current of a circuit is possible, which is especially important in sample-and-hold circuits.</p><h3>Working Principle</h3><p>Resistor networks are a construction technique to simplify the implementation of multi-resistor circuits using single packages, and as such, are based on the principle of resistance. A resistor network, like the 4308H-101-224LF, essentially consists of multiple resistors connected in series or parallel, and can be used to represent complex resistance values.</p><p>Resistor networks such as the 4308H-101-224LF also contain multiple isolated resistors. An isolated resistor is one that does not have any electrical connections to other components, or between its two terminals. The value of the isolated resistor depends on the number of resistors in it, their values, and the overall resistance of the resistor network.</p><p>In addition to the resistance produced by the resistor network, these networks are also used to produce certain voltage dividers. Voltage dividers consist of two or more resistors connected in parallel. As the voltage is divided over the resistors, the voltage at the output of the resistor network is determined by the ratio of the resistors. This enables resistor networks such as the 4308H-101-224LF to be used as level shifters, for example, when the voltage of a circuit needs to be shifted to a different level.</p></div>
