Resistor Networks, Arrays

Resistor networks, arrays, and configurations are used to split a current between several paths or to independently control several isolated loads at various currents. The 4416P-1-330LF is one such example. This resistor network is an integrated circuit that has 16 independent identical resistors with identical 3.3 ohm resistances. These resistors can be used to split the current between several paths.

The 4416P-1-330LF resistor network is built on a four-pin configuration, making it suitable for simple resistive networks with few components. The four pins are:

• Pin 1 – VREF
• Pin 2 – VOUT
• Pin 3 – VIN
• Pin 4 – GND

The resistor network works by connecting the circuit’s DC voltage or current source to both the reference pin and to an input pin. When this happens, the reference and input pins establish a voltage potential across the resistor network. At the same time, the incoming source voltage or current is split among the sixteen resistors. This divide-by-eighteen process splits the current into two different parts: one component going out to the output pins and the other component remaining on the network.

Aside from being used for splitting current paths, the 4416P-1-330LF resistor network can also be used to provide isolation between several isolated loads at different currents. In these applications, the reference pin is connected to the input or source voltage and each output or load is connected to its own pin. As the source voltage is established, the low-impedance resistors in the network form what’s called a constant voltage isolation barrier between the pins. This isolation barrier prevents direct currents from flowing through the network and potentially damaging the loads.

In summary, the 4416P-1-330LF resistor network is a four-pin integrated circuit that is used to split the source voltage or current between several paths or to isolate several loads at different currents. This resistance network has 16 identical 3.3 ohm resistors that are used to divide the incoming current evenly. This particular resistor network is often used in resistive networks with limited components.
