The MCP4442T-103E/ST from Microchip Technology is a digital potentiometer designed for various electronic applications. This device offers 4 independent resistor networks, each configurable as a rheostat, with a nominal resistance of 10k Ohms and 129 taps for precise control.
Key electrical specifications include a wide operating voltage range from 1.8V to 5.5V and a low wiper resistance of 75 Ohms typical. The I2C serial interface supports multiple communication speeds, allowing for high-speed read/write operations to the wiper and non-volatile memory. The potentiometer also features WiperLock™ technology with 5 general-purpose memory locations for automatic recall of saved wiper settings.
This digital potentiometer is housed in a 14-TSSOP surface-mount package, measuring 0.173 inches (4.40mm) in width. It operates across an extended temperature range of -40°C to +125°C, making it suitable for demanding environments. The device includes features like hardware and software write protection, a reset input pin, and high-voltage tolerant digital inputs up to 12.5V.
