Microchip Technology, Inc. Digital Potentiometers MCP4242T-503E/UN

The MCP4242T-503E/UN is a dual digital potentiometer featuring a non-volatile memory that allows for automatic recall of saved wiper settings. It operates with a SPI interface, supporting speeds up to 10 MHz and offering both potentiometer and rheostat configurations. The device provides a resistance range of 5 k,Ѷ to 100 k,Ѷ with a resolution of 7-bit (128 steps) or 8-bit (256 steps). It has a low wiper resistance of 75,Ѷ and operates over a wide voltage range of 2.7V to 5.5V, with a typical current consumption of 2.5 ¬µA when inactive. The MCP4242T-503E/UN is designed for extended temperature applications, functioning within a range of -40¬8C to +125¬8C. It includes features such as WiperLock,Ñ¢ technology for securing calibration settings, a shutdown pin for terminal disconnect, and both hardware and software write protection options. The device is suitable for applications requiring precise control and reliability in varying environmental conditions.
