A digital potentiometer, also known as a digipot, is an analog device used to control the resistance of an electrical pathway in a circuit. The MAX5160NEUA+T digital potentiometer is a superior autonomous digital-to-analog converter that features user-programmable breakpoints, electronic control, and temperature compensation. It has two digital logic pins — chip select (CS) and write enable (WE) — and one analog input pin.

The MAX5160NEUA+T Application Field and Working Principle

The MAX5160NEUA+T digital potentiometer is designed with a primary application field in data acquisition systems. It can be used to control various transducers, sensors, and amplifiers, as well as to digitally control analog signals such as audio signals. It can also be employed in situations where an adjustable resistor is needed to adjust circuit parameters such as voltage gains, time constants, and so on.

The working principle of the MAX5160NEUA+T digital potentiometer is fairly simple. When a CS signal is sent to the device, it activates its “read” mode. When a WE signal is received, the “write” mode is activated. The resistor is set to the desired resistance value by sending a digital-to-analog (DAC) code through the WE pin. After the code is received, the resistance is adjusted proportionally.

The MAX5160NEUA+T digital potentiometer includes an 8-bit serial-in (SI), digital-to-analog converter, which allows for a range of 256 digital codes for independent wiper position setting. It is based on the MAX5160 nonvolatile DAP circuit that can be used for enhanced accuracy, speed and temperature coefficient referencing. The device has a fixed resistor value, a resistor temperature coefficient, EEPROM memory for programming, and a voltage conditioner.

The MAX5160NEUA+T can be used in a variety of applications with various sensing and control needs. It can be used in automotive, industrial, and consumer-electronic applications where linear or logarithmic control of potentiometers is required. It is also extremely useful in such applications as membrane switches, hot and cold temperature sensors, pressure sensors, gas sensors, current sensing, and temperature sensing.

Conclusion

The MAX5160NEUA+T digital potentiometer is easy to use yet highly versatile and applicable for many data acquisition applications. It allows for precise control of numerous transducers, sensors and amplifiers and provides a reliable, high-performance digital-to-analog output. The 8-bit serial-in, digital-to-analog converter also provides a range of 256 digital codes for independent wiper position setting, making it an ideal choice for applications ranging from automotive to industrial and consumer-electronic applications.
