Application field

MAX5491WC30000+T is a product of the MAX5491 family of digitally controlled resistor networks. The product provides 30 ohms to 300K ohms in 32 steps with 25ppm accuracy. It is especially suitable for design with wide temperature range, low noise and low power consumption. The application fields for it include, but not limited to:

• audio and video signal processing
• telecom applications
• datacom/networking systems
• medical instrumentation
• test and measurement equipment

Working Principle

MAX5491WC30000+T consists of an array of resistors with a digitally controlled wiper. The capacitance of the board is controlled by a unique system that integrates configurable switching transistors. By using this technology, the MAX5491WC30000+T is able to provide precise galvanic isolation between the input voltage and the output voltage, and also providing topology control. In other words, the resistance between two nodes can be easily adjusted by controlling the inputs.

Apart from the interface, the MAX5491WC30000+T also comes with an on-board decoder. This decoder enables the user to control the resistance between two nodes over a wide range of values from 30 ohms to 300K ohms. The user can also take advantage of one-wire tuning technology to easily adjust the resistance between two nodes as required.

Conclusion

In conclusion, the MAX5491WC30000+T is an optimal example of Resistor Networks, Arrays in the current market. Its wide temperature range, low noise and low power consumption makes it ideal for audio and video signal processing, telecom applications, data-com/networking systems, medical instrumentation and test and measurement equipment. In addition, the on-board decoder enables the user to adjust the resistance between two nodes over a wide range of values from 30 ohms to 300K ohms.
