Resistor Networks, Arrays

The AF164-FR-0738R3L is a resistor network chip targeted at the board-level integration of resistors in a variety of circuits. This combination of up to 16 resistors on one chip can be used for the implementation of resistor circuits in a much more cost-effective and compact manner. It is designed to simplify the design of resistor circuits, reduce cost, and reduce the complexity of printed circuit boards.

The AF164-FR-0738R3L comes in two different versions: one with four channels, and one with eight channels. Each channel contains four resistors, allowing for up to sixteen resistors in total. The resistors are connected in a series-parallel combination, which allows for the flexibility to adjust the resistance values over a wide range, while maintaining a high accuracy. The use of 0.03% accuracy resistors ensures that the resistance values are as accurate as possible.

The AF164-FR-0738R3L is capable of operating at a maximum of 200V and 2.2A. It also has an internal thermal overload protection, which protects it from over-current and temperature hazards. The chip also has a built-in lockout protection, which prevents the chip from switching on when an incorrect voltage is applied. This is useful in preventing unintentional short circuits, providing protection for the chip as well as the board where it is installed.

The working principle of the AF164-FR-0738R3L is relatively simple. Each resistor is connected in series with the next, resulting in a series-parallel connection. This connection allows for the adjustment of different resistance values for different circuits. The current through the chip can be controlled by changing the resistance values of each resistor, allowing for a wide range of output voltage and current levels.

The AF164-FR-0738R3L is a versatile component that can be used in a variety of applications. It is suitable for use in motor controllers, audio amplifiers, power supplies, and many other circuits requiring a combination of resistors. It can also be used to reduce the number of discrete resistors required in a circuit, reducing the amount of board space used and allowing for cost savings.

In summary, the AF164-FR-0738R3L is an ideal resistor network chip for use in board-level resistor networks and applications. It allows for cost savings and simplifies the design of resistor circuits. Furthermore, it offers flexibility and design advantages, making it a great choice for many applications.
