Resistor networks and arrays consist of multiple resistors connected in varying topologies. These networks are designed to alter the output voltage and/or current of a circuit by offering varying resistance levels in different configurations. The RT1430B6TR7 is a unique resistor array, and its application field and working principle are discussed in this article.

Applications

This resistor array is designed for low power applications, where the power dissipation is less than 100mW. Its size of 1430 mils x 1120 mils x 120 mils is optimized for optimal performance. This array is suitable for telecom applications as well as dual in-line memory module (DIMM) applications in personal computers, where low power consumption is desired.

Working Principle

The RT1430B6TR7 is composed of twelve surface-mounted pins, each with a resistance value of 87.5 ohms. The resistors are arranged into four blocks, each containing three pins. The pins are connected together in a particular order to form an array of three series and five parallel resistances. The series resistances form a ladder network which provides a steady output voltage of 0-4.4V. The parallel resistances are formed to minimize the voltage drops between the blocks. This ensures that the entire array operates at the same voltage.

In order to achieve optimal output voltage levels, the RT1430B6TR7 includes a local voltage regulator. This regulator is controlled by a control logic circuit which is used to adjust the output voltage level. The local voltage regulator ensures that the output voltage regulates regardless of any changes in the input voltage.

In addition, the RT1430B6TR7 includes an on-chip temperature range control circuit. This circuit ensures that the temperature of the resistor array stays within the given operating range. This is of great importance, as temperature changes can have a significant impact on the performance of the resistor array.

Conclusion

In conclusion, the RT1430B6TR7 is a unique resistor array which is suitable for low power applications. It is composed of twelve surface-mounted pins, each with a resistance value of 87.5 ohms. The array is composed of three series and five parallel resistances, and the output voltage can be regulated through the use of a local voltage regulator. Furthermore, an on-chip temperature range control circuit is included to ensure that the resistor array stays within its operating ranges.
