MCP4461-104E/ST is a digital potentiometer, which is mainly used to measure voltage, temperature, etc. It is commonly used in data acquisition as well as various analog-to-digital, digital-to-analog, and digital signal processing applications. MCP4461-104E/ST has a voltage input range of 0 to 5V, and a temperature range of 55°C to 125°C. It features an SPI interface, a 16-bit resolution, and a two-wire selector. Its two-wire selector allows a user to select either the internal voltage reference or the external voltage reference, depending on the application.

MCP4461-104E/ST is a potentiometer consisting of three terminals – a pot core, a wiper, and a ground or return connection. The pot core is connected to the voltage source, while the wiper is connected to the output circuitry. The pot core and wiper are both connected to the ground connection. When the wiper is moved across the resistive track of the pot core, the resistance value varies and thus provides a varying voltage or current at the output point.

The MCP4461-104E/ST works by setting the voltage from the pot core to the wiper and adjusting the resistance. When the resistance of the pot core changes, the voltage on the wiper tracks this change. Since the voltage at the output point is proportional to the resistance of the pot core and the wiper, the output voltage will increase or decrease, based on the movement of the wiper. The MCP4461-104E/ST is also able to measure the temperature of the environment since the resistance value of the pot core changes with the temperature. This allows the device to provide accurate and reliable temperature readings.

In addition to measuring voltage, the MCP4461-104E/ST also provides digital control with its SPI interface. Through the SPI interface, the user can precisely control the pot core resistance. The 16-bit resolution provides a wider range of resolution for controlling the device. The SPI interface also allows the user to send commands to the device from an external controller.

The MCP4461-104E/ST is a versatile and reliable device that can measure voltage and temperature, provide digital control of the pot core, and even act as a precision voltage reference. It is suitable for use in data acquisition as well as analog-to-digital, digital-to-analog, and digital signal processing applications. Its two-wire selector allows the user to select either the internal voltage reference or the external voltage reference, depending on the application.
