The MCP4461T-503E/ST is a Digital Potentiometer (DP) in the Data Acquisition category that is designed specifically for low-power, low-voltage applications.

The device features an I2C interface, allowing it to be accurately programmed, as well as a 256-position wiper allowing it to control analog signals with 256 steps of resolution. It also has selectable 4-wire I2C-bus compatible interface modes, active-low chip select input, and a low power shutdown function. The device provides a non-volatile memory containing calibration and configuration information for up to 4 different devices. This data is stored in an on-chip EEPROM memory and can be programmed over the I2C bus.

The MCP4461T-503E/ST Digital Potentiometer has a wide range of applications in digital audio, power management, instrumentation, medical, communications and processor control. The device is ideal for use in high-resolution audio systems, signal routing, signal conditioning and low-power power supply design. Its low-voltage operation makes it ideal for use in portable applications. Additionally, its small package size and low power make it an ideal choice for embedded designs.

The MCP4461T-503E/ST Digital Potentiometer operates in two modes; Normal Mode, in which the wiper will move in response to the voltage applied to the SD pin, and Active Mode, in which the wiper will move in response to the control register. When powered down, the SD pin voltage will be zero. In Active Mode, the device can be programmed for a desired wiper position by writing the desired value to the control register.

The digital potentiometer also has an internal latch which, when enabled, sets the wiper at the last programmed wiper position. The device has an absolute wiper tracking accuracy of +/- 10 mV, a monotonic wiper tracking accuracy of +/-25 mV, and a maximum offset of +/-20 mV between connections. The digital potentiometer also has an adjustable gain of 0-4x, and an adjustable slew rate of 0-2x.

It is important to note that the MCP4461T-503E/ST Digital Potentiometer has a maximum supply voltage rating of 7.5V and a minimum operating temperature of -30 °C. It is best to take care to ensure that these specifications are not exceeded, as the device may become damaged if these parameters are exceeded.

In conclusion, the MCP4461T-503E/ST Digital Potentiometer is an ideal device for use in low-power, low-voltage applications. Its wide range of applications, low-power shutdown function, adjustable gain and slew rate, and non-volatile memory, make it an excellent choice for users looking for a reliable, low-power digital potentiometer.
