Microchip Technology, Inc. Digital Potentiometers MCP4261T-103E/ST

The MCP4261T-103E/ST is a digital potentiometer featuring a 10 k,Ѷ resistance with 257 taps, designed for applications requiring precise resistance adjustments. It operates via a Serial Peripheral Interface (SPI) with a maximum clock speed of 10 MHz, supporting modes 0,0 and 1,1. The device includes non-volatile memory, allowing for automatic recall of wiper settings and features WiperLock,Ñ¢ technology for secure calibration settings. This component offers a low wiper resistance of 75,Ѷ and operates within a voltage range of 2.7V to 5.5V, with a typical current consumption of 2.5 ¬µA when inactive. It is suitable for a wide temperature range from -40¬8C to +125¬8C, making it versatile for various environmental conditions. The MCP4261T-103E/ST also includes features such as hardware and software write protection, brown-out reset protection, and a shutdown pin for terminal disconnect. Engineers considering this product should note its extended temperature range, low power consumption, and robust SPI interface, which make it suitable for applications in data acquisition and control systems.
