Digital potentiometers have applications in the field of data acquisition due to their ability to quickly adjust resistances in a circuit. The MCP4261T-103E/ML is an especially versatile digital potentiometer that is suitable for a wide variety of applications.This device offers a linear taper and a resistance range of 10 KΩ, however it is also available with a logarithmic taper and four other resistance ranges. It can be operated with a variety of voltage supplies, ranging from 1.8 to 5.5 Volts, and is available in an 8-pin SOIC package.The MCP4261T-103E/ML features an on-chip non-volatile memory, which retains the wiper position upon power-down. This memory is written and read through the I²C protocol, which makes it ideal for applications involving remote adjustments or automated operations.The wiper of the MCP4261T-103E/ML is controlled by two external resistors, RS and RD. These resistors set the step size of the device and are used to set the resistance between terminals R1 and R2. The resistance between R1 and R2 can be adjusted in 128 steps by the on-chip digital-to-analog converter (DAC).The current draw of the MCP4261T-103E/ML is extremely low, which makes it ideal for battery-powered applications. It draws only 1μA during operation and less than 0.1μA in shutdown mode. This device also features a resistive fault detection circuit that prevents damage to the device in the event of an overload.The MCP4261T-103E/ML is a robust device that has a wide range of potential applications. These include remote temperature control systems, computer-controlled robotics, and motor position control systems. Its low power consumption, robustness, and fast wiper position control make it an ideal device for these types of applications.
