Microchip Technology MCP4252T-104E/UN Digital Potentiometer

The MCP4252T-104E/UN is a versatile digital potentiometer designed by Microchip Technology, a leader in microcontroller and analog semiconductors. This compact and highly integrated component is ideal for applications requiring variable resistance settings controlled through a digital interface.

The MCP4252 series features a dual-channel configuration, with each potentiometer offering 7-bits (128 wiper steps) of resolution. This allows for precise adjustment of the resistance between the terminal ends and the wiper, which can be particularly useful in calibration and signal conditioning applications.

The MCP4252T-104E/UN operates with a nominal resistance of 100 kΩ, providing a wide range of adjustability to meet the needs of various circuits. It interfaces with microcontrollers via an SPI-compatible serial interface, which enables easy integration into existing digital systems and provides a straightforward communication channel for resistance adjustments.

This digital potentiometer is designed for operation over a broad voltage range, from 2.7V to 5.5V, making it suitable for both 3.3V and 5V logic systems. Its extended temperature range ensures reliable performance in diverse environments, with operational capabilities from -40°C to +125°C.

The MCP4252T-104E/UN comes in a compact 14-TSSOP (Thin Shrink Small Outline Package) that is RoHS compliant, ensuring adherence to current environmental standards. The device also features non-volatile memory for storing the wiper position, which means the last set resistance value is retained even after the power is cycled.

Given its digital control, precision, and package size, the MCP4252T-104E/UN is an excellent choice for applications such as adjustable power supplies, LCD screen calibration, audio control, and industrial automation systems where digital control of resistance is advantageous.

Microchip Technology's commitment to quality and performance is evident in the MCP4252T-104E/UN, making it a reliable and efficient solution for designers looking to enhance their electronic designs with digital potentiometer functionality.
