The MCP4452T-103E/ST is a digital potentiometer that combines standard features of the MCP4451T family with integrated EEPROM memory to store the wiper setting. It is a device that offers 256 tap locations to provide output voltage settings digitally and over a wide resistance range. The device is designed to be used in a variety of applications in consumer, industrial, communication and automotive markets.

The MCP4452T-103E/ST device is suitable for applications such as adjustable reference voltages, DAC linearization, boost/buck control, programmable gain control and many more. It can be used to replace mechanical potentiometer and other user-adjustable devices. The device can also be used for position sensing, potentiometer emulation and variable resistor functions. It is available in an 8-pin PDIP, SOIC and TSSOP, and 7-pin UDFN packaging.

The device offers 8 wiper address pins that can be used to store each wiper position. A non-volatile EEPROM feature of the device allows the user to store and recall the wiper setting. The device contains two digital potentiometers that are connected in series. The two potentiometers can be set to different resistance values. This feature enables the user to adjust the voltage at the middle nodes of the series connection. The device offers a maximum resistance of 100K Ohms at each end terminal and a total resistance of 200K Ohms between both of them.

The device features a low-power shutdown mode which can be used for power saving purposes. It also has a low-power standby mode which cuts down the power consumption significantly. The device is also equipped with an on-board clock that can be used to control the settings of the potentiometers. The device has a voltage supply of 2.7 to 5.5V and can operate at temperatures ranging from -40 to +85 degrees Celsius.

The MCP4452T-103E/ST has a wide range of digital potentiometer applications including adjustable reference voltages, DAC linearization, boost/buck control, programmable gain control, position sensing, potentiometer emulation and variable resistor functions. These applications provide users with the option of controlling, adjusting and modifying voltage ratios, current flows and settings digitally. This digital potentiometer is an attractive choice for those who prefer a wide range of resistance values in their design.

The MCP4452T-103E/ST is a versatile digital potentiometer that offers a wide range of features and applications. This two terminal device is suitable for all types of digital settings and resistance values, and presents an attractive option for an adjustable voltage reference in power supplies, linearization in DACs and many other applications.
