The Microchip Technology MCP4442-104E/ST is a quad rheostat digital potentiometer designed for various electronic applications. It offers a nominal resistance of 100 kΩ with 129 taps, providing fine control. The device supports an I2C serial interface, enabling high-speed read/write operations to the wiper and EEPROM.
This digital potentiometer operates within a voltage range of 1.8V to 5.5V and has an extended operating temperature range of -40°C to +125°C. Key features include non-volatile memory for automatic recall of saved wiper settings and WiperLock™ technology. The low wiper resistance of 75 Ω (typical) and a typical temperature coefficient of 150 ppm/°C ensure reliable performance.
The MCP4442-104E/ST is available in a 14-TSSOP package, suitable for surface mounting. It also includes features like hardware and software write protect, a reset input pin, and high-voltage tolerant digital inputs up to 12.5V, making it a versatile component for embedded systems.
