Resistor networks, arrays, and the AF164-FR-0762RL are a type of integrated circuit component that contain several interconnected resistors. They are usually used to provide feedback to a control system to adjust the response of the system to different conditions or to provide an impedance match between different elements of a circuit. The particular AF164-FR-0762RL model is a miniature seven position, single in-line resistor network. It is made from laser trimmed film resistors and is specifically designed to be used in a wide variety of applications such as signal conditioning, load balancing, and impedance matching. The device allows for a high precision of resistance value selection, making it useful in applications where precision is important. It also provides excellent thermal stability, making it ideal for high temperature operation.

The unique feature of the AF164-FR-0762RL comes from its seven position resistor array. The resistors are placed in parallel and can be individually enabled or disabled using a control pin. This means that the resistance of the device can be easily adjusted to suit the needs of the particular application. For example, in a signal conditioning application, the resistors can be configured to provide different gains over different frequency ranges. This flexibility makes the AF164-FR-0762RL an ideal choice for many applications.

The AF164-FR-0762RL is built from four resistors in a so-called “tetrahedral” configuration. This means that the four resistors are connected in such a way that each has two resistors in parallel with it, forming a three dimensional structure. This configuration ensures that the device provides good thermal properties, meaning that the device’s resistance is not affected by temperature. The four resistors are laser trimmed for precision and to allow for tight tolerance, meaning no two devices of the same model will provide exactly the same resistance. Additionally, the unit is offered in a wide range of resistance options, providing an even wider range of possibilities for users.

In terms of working principle, the AF164-FR-0762RL provides a simple voltage divider circuit. In this circuit, the voltage at the output is determined by the ratio of the two resistors connected in series. These resistors are then connected to a control pin. The current through the resistor is then controlled by the control pin. In this way, the resistance of the device as a whole can be adjusted depending on the signal applied to the control pin, meaning it can be adapted for various applications. The precise adjustment of the resistance is achieved by the laser trimming of the four resistors, allowing for high precision and stability.

Overall, the AF164-FR-0762RL provides a miniature, highly precise resistor network capable of being used in a number of applications. Its seven position resistor array allows for flexibility and the four laser trimmed resistors ensure excellent thermal stability and high precision. The device provides excellent value for signal conditioning, load balancing, and impedance matching. It can be easily adjusted to suit the application using its control pin and its miniature size makes it ideal for use in space constrained areas.
