The MCP4252T-103E/UN is a digital potentiometer, having an integrated non-volatile memory for the storage of the count value. This chip is very useful in data acquisition applications as it allows for direct and programmable changes of the resistance value, depending on the use and requirements of a system. It is part of Micropower’s family of digital potentiometers, offering high performance, low power, and low noise performance for data acquisition related applications.

Digital potentiometers, sometimes referred to as adjustable digital chips, provide the functionality of a manually adjustable resistor with the convenience of an easy to program digital chip. They are ideal for applications which require voltage or resistance control over a range of values. The MCP4252T-103E/UN is a bipolar digital potentiometer that has a power range of +/–20V and a 50-kΩ resistance range. It is commonly used in data acquisition and control applications such as alternating power supplies, voltage regulators, and digital thermometers. Its programmable discrete resistance values make it suitable for various applications.

The MCP4252T-103E/UN works by implementing a unique 256 step wiper control logic which can be set to program specific resistance values. It is composed of two logarithmic rheostats, and a non-volatile memory circuit that stores the resistance setting. The wiper controls the resistance between the acceleration and wiper terminals. The memory stores the resistance setting information for non-volatile operations. This data is then transferred to the wiper controls via a shift-register interface. The resistance value is stored in a flash memory which is visible through the serial interface.

The MCP4252T-103E/UN is a low-noise, low-power digital potentiometer which can be used in a variety of data acquisition applications. Its adjustable range makes it suitable for measuring voltage, current, resistance, and other conditions in different environments. Furthermore, it can be configured to measure parameters such as temperature, humidity, pressure and acceleration. It is also suited for controlling the brightness of LEDs and LCDs, as well as switching on and off different system components.

The MCP4252T-103E/UN is a low-cost and versatile digital potentiometer which is used to measure or quantify a variety of different parameters. It is an efficient and cost-effective solution for various data acquisition and control applications. The adjustable range, non-volatile memory, low-power consumption and non-volatile memory make it a great choice for many applications.
