Resistor networks also known as resistor arrays feature multiple resistors connected together in a circuit pattern. They primarily act as a voltage divider, which split the voltage in a circuit to smaller amounts. Resistor networks and arrays are a useful item in the design engineer's component kit. Arrays are simply a subset of networks, in which all elements have the same ohmic value. The network is especially beneficial when the design needs multiple pull-up, line-termination, or gain-setting resistors.
