Resistor Networks, Arrays are among the most common form of integrated resistor in the industry. The 4116R-2-203LF is one of such networks/arrays available in the market. The 4116R-2-203LF is a small, package size, low resistance 4-resistor array. The application field and working principle will be discussed in the following sections.

Application Field

The 4116R-2-203LF is mainly used in signal conditioning applications such as amplifier output level matching and provision of high frequency noise cancelling technique. It is suitable for use in low noise audio editing applications such as computers and analog telephone systems. It can also be used for attenuation or division of signals when connected across various stages of amplifiers. It is commonly used in applications that require precision voltage/current splitting and impedance matching.

The 4116R-2-203LF is also used in many automotive and aerospace applications, such as temperature sensing, on-board instrumentation, and A/C system controllers. Low profile chip arrays with multiple independent outputs can also be used to provide multiple input power sources for constant current drive.

Working Principle

The 4116R-2-203LF uses two independent low-value resistors connected in parallel to form an array. The individual resistors are designed to carry equal current load, and the resistance of the array is equivalent to the parallel combination of the two resistors. That is, R=(R1*R2)/(R1+R2).

The 4116R-2-203LF is designed for use in series with a device needing biasing such as a temperature sensor or a pressure sensor. When a voltage signal is applied across the input of the 4116R-2-203LF, the result is a voltage divider and a current divider in parallel. The voltage divider acts to reduce the applied voltage, and the current divider acts to provide a constant current for the device requiring the biasing.

The overall resistance of the 4116R-2-203LF is adjustable by changing the value of the individual resistors. This permits the circuit designer to set the output voltage of the divider, and the current requirement of the powered device. It is important to note that the actual achieved resistance will depend on the used resistor values, the load current, and the power of the signal. It is also important to note that the 4116R-2-203LF contains noise cancellation circuitry that allows it to be used for low-noise audio applications.

Conclusion

The 4116R-2-203LF has many applications in both analog and digital designs. It is used as a voltage divider, impedance match, and level shifter. It is also used for noise cancellation applications in low-noise audio systems. The adjustable resistance makes this device a very versatile resistor array for a variety of applications, and its small package size makes it suitable for applications where space is limited.
