Data Acquisition - Digital Potentiometers

Digital potentiometers are devices that are used in data acquisition applications to digitally adjust the resistance between two nodes, as opposed to the traditional mechanical potentiometers. One such digital potentiometer, the X9261UV24I-2.7T1, is a 3-terminal device, that features a resolution of 256 steps, a nominal resistance of 10kΩ, and a temperature range of -40°C to +125°C.

Features

The X9261UV24I-2.7T1 features an integrated plus-minus pulling feature that allows adjacent channels to interact and independently adjust their respective terminal resistance values. Furthermore, this device also features an external control mode which allows other ICs to interact with the device’s RAM register via an external serial interface. The resistance values of the device can either be adjusted through the increment and decrement pins or through the external serial interface.

Applications

The X9261UV24I-2.7T1 is a highly versatile digital potentiometer that is suitable for applications that require accurate control of resistance values. The device is ideal for applications such as audio gain/attenuation and for controlling volume, as well as for applications that utilize Closed Loop Control. Additionally, this device is also used in temperature control systems, robotics, and in digital processing applications.

Working Principle

The X9261UV24I-2.7T1 is an I2C compliant device, which is controlled by three connections connected to the chip, which are the SDA, SCL, and VDD pins. The device is an active two-terminal device, that can adjust its terminal resistances through the increment and decrement pins or through the external serial interface (I2C).The device features a 256-position 7-bit EEPROM cell memory configuration, which is used to store a 7-bit resistance value that corresponds to the desired resistance value. In order to adjust the resistance in either direction, the voltage of the increment pin is adjusted. When the voltage increases, the resistance value increases. Conversely, when the voltage decreases, the resistance value decreases.The device can also be controlled via the external serial interface. Once connected, the processor will send a value to the device, which is then stored in the EEPROM cell memory. This is then converted to a single resistive value in order to adjust the resistance of the device in either direction.

Conclusion

The X9261UV24I-2.7T1 is a highly versatile digital potentiometer that is well suited to data acquisition applications. With a resolution of 256 steps and a temperature range of -40°C to +125°C, this device is well suited to a range of applications. With onboard plus-minus pulling features and an external control mode that allows control through the I2C interface, this device offers many features and is a great choice for applications that require accurate control of resistance values.
