The DS3901E+ from Maxim Integrated is a versatile, low-voltage, dual nonvolatile (NV) digital potentiometer. Designed to operate over a wide voltage range of 2.7V to 5.5V, this device offers a unique combination of nonvolatile memory and digital control flexibility, making it ideal for a wide array of applications that require precise calibration and adjustment.

With its nonvolatile memory, the DS3901E+ can recall the last position before power-down, ensuring reliable and consistent performance across power cycles. This feature is particularly useful in applications where calibration settings need to be maintained, such as in audio volume control, bias adjustments, and LCD screen calibration.

The device features two 256-position, linear-taper digital potentiometers, allowing for fine-grained control over resistance settings. This high level of precision ensures that the DS3901E+ can meet the needs of even the most demanding applications. The potentiometers are also designed to provide low temperature coefficient and high tolerance, ensuring stability and accuracy over a range of environmental conditions.

Communication with the DS3901E+ is facilitated through a simple 2-wire serial interface that is compatible with I2C bus specifications, making it easy to integrate into existing systems. The compact package size of the DS3901E+ also makes it an excellent choice for space-constrained applications.
